A fall can cause sciatica, the pain that runs from the low back or buttock down the back of the leg.1CME Journal Geriatric Medicine. Study of Causes, Symptoms, and Diagnosis of Lumbar Disc Herniation Sciatica describes where the pain travels, not the injury behind it, and a hard landing can irritate the nerve at several points between the spine and the thigh. Most sciatica, including the kind that follows an injury, settles over weeks to months without surgery.2PubMed Central. Diagnosis and treatment of sciatica
How a Fall Can Injure a Spinal Disc
Each disc between your vertebrae has a tough outer ring and a soft, gel-like center. A sudden impact, such as landing hard from a height, squeezes the disc with a force it isn’t built for.3Thomas J. Henry Law. Can a Fall in Texas Cause a Herniated Disk? If that force is too strong or comes at an angle, the outer ring can tear.4Thomas J. Henry Law. Can a Fall in Texas Cause a Herniated Disk? The soft center can then push through the tear, which doctors call a herniated disc.5Thomas J. Henry Law. Can a Fall in Texas Cause a Herniated Disk? From there, the bulge can press on a nearby nerve root that feeds the sciatic nerve, sending pain down the leg.
Falls are a real but less common cause. Most herniated discs come from gradual wear over years, not a single injury.6CME Journal Geriatric Medicine. Study of Causes, Symptoms, and Diagnosis of Lumbar Disc Herniation Still, falls, car crashes and sports injuries can tear a disc suddenly.7CME Journal Geriatric Medicine. Study of Causes, Symptoms, and Diagnosis of Lumbar Disc Herniation Many adults already have some disc wear, so a fall can tip an aging disc into a herniation. A weakened outer ring can give way under a modest jolt, such as sitting down hard on a step.
Whether a torn disc causes leg pain depends on where the bulge goes. One that pushes toward the nerve root hurts the leg, while one that bulges elsewhere may cause only back pain or nothing.
The leg pain may not start right away. At the moment of the fall you may feel pain only in the back or buttock, and swelling around a torn disc builds over the first day or two. Leg pain that shows up later can still come from the fall, so note the day your symptoms began.
Sciatica from a disc usually feels like burning or electric pain running below the knee, often into the foot. It is typically on one side only. Coughing, sneezing or sitting for a long time can make it worse, and numbness or tingling may follow the same line down the leg.
Other Ways a Fall Can Cause Sciatica-Like Pain
A direct blow to the buttock in a fall can bruise the sciatic nerve itself.8PubMed. Traumatic sciatic nerve contusion In nerve injuries to the legs and lower back after trauma, the sciatic nerve is the one most often hurt.9PubMed. Traumatic lower extremity and lumbosacral peripheral nerve injuries in adults: Electrodiagnostic studies and patients symptoms A blow can also inflame a deep buttock muscle the sciatic nerve runs beside or through.10PubMed. Posttraumatic piriformis syndrome: diagnosis and results of operative treatment
A bruised nerve or irritated buttock muscle tends to hurt most where you landed, and the pain may change with pressure on that spot or with certain hip positions. Disc pain more often shifts with spine movements like bending forward, or with coughing, since those change pressure on the nerve root. These patterns are clues rather than proof, and overlap is common, so a doctor’s exam matters more than self-sorting.
The pelvic joint can also mimic sciatica. The sacroiliac joint, where the spine meets the pelvis, can cause leg pain that looks just like disc sciatica.11PubMed Central. Sciatica-like symptoms and the sacroiliac joint: clinical features and differential diagnosis People whose leg pain came from this joint more often reported a fall onto the buttocks.12PubMed Central. Sciatica-like symptoms and the sacroiliac joint: clinical features and differential diagnosis Its pain more often spreads into the groin, and it was more common in women.13PubMed Central. Sciatica-like symptoms and the sacroiliac joint: clinical features and differential diagnosis
Broken vertebrae matter most for older adults. A fall can crack a weakened vertebra, and a crack in the lower back can trigger sciatic pain.14Arizona Pain. 13 Vertebral Compression Fracture Symptoms To Watch For An older adult with thin bones who has sciatica after even a minor fall needs an X-ray.
A cracked vertebra is easy to miss because it can feel like a bad muscle strain. Sharp pain over one spot in the middle of the spine that eases when lying down but flares on standing is worth reporting. Older adults, people with osteoporosis, and those on long-term steroid medicines have weaker bone and can fracture from a low fall. Only imaging confirms a fracture.
The cause matters because it changes treatment. A disc may need nerve-focused care or, rarely, surgery. Buttock-muscle or pelvic joint pain responds to targeted stretches or injections, and a fracture may need bracing or bone treatment. Treating the wrong source can leave the pain unchanged.
Warning Signs That Need Emergency Care
Certain symptoms after a fall point to cauda equina syndrome, severe pressure on the nerve bundle at the base of the spine:
- Saddle numbness: loss of feeling in the inner thighs, buttocks and genitals is the hallmark sign.15Legent Spine. Cauda Equina Syndrome: Critical Red Flags Every Patient Should Know
- Bladder changes: not feeling when your bladder is full, trouble starting urination, or losing bladder control.16Legent Spine. Cauda Equina Syndrome: Critical Red Flags Every Patient Should Know
- Bowel changes: losing bowel control or not feeling the need to go.17Legent Spine. Cauda Equina Syndrome: Critical Red Flags Every Patient Should Know
- Worsening weakness: a leg or foot that is getting weaker.
Severe weakness and loss of bladder or bowel control are among the few reasons surgery is done for sciatica.18Mayo Clinic. Sciatica – Diagnosis and treatment Go to an emergency department rather than waiting for a routine appointment.
In everyday terms, saddle numbness may first show up as odd sensations when wiping after using the toilet or when sitting on a hard seat. Bladder trouble can look like leaking without noticing, or straining to pass urine even when you feel full. Weakness may appear as a foot that slaps or drags when you walk, or a leg that gives way on stairs. These changes can come on over hours to days after a fall, so recheck yourself the day after, not only right away.
Some fall-related signs go beyond nerve trouble. Severe back pain after a hard fall can mean a fracture. Back pain with fever or unexplained weight loss needs prompt checking. A head strike, confusion, or blood thinner use calls for emergency review, and pain in both legs is more concerning than pain in one.
In the emergency room, describe how you fell and what you landed on. Report bladder, bowel and saddle changes plainly, even if it feels awkward, and say when each symptom began. Bring a list of your medicines, especially blood thinners.
How a Doctor Checks Sciatica After a Fall
The key hands-on check is the straight leg raise. You lie flat while the doctor lifts your straight leg.19University of Maryland School of Medicine. Performing Straight Leg Raise Test for Sciatica The test is positive if lifting between about 30 and 70 degrees sends pain below the knee.20University of Maryland School of Medicine. Performing Straight Leg Raise Test for Sciatica It catches about 9 in 10 people with true sciatica yet is often positive in people without it.21University of Maryland School of Medicine. Performing Straight Leg Raise Test for Sciatica So a negative leg-raise test makes disc-related sciatica less likely, while a positive one needs other findings to confirm it.
The rest of the exam fills in the picture. The doctor tests strength by having you walk on your heels and toes, checks reflexes at the knee and ankle, and uses light touch to map numb areas to a particular nerve. Pressing on the buttock or pelvis checks for buttock-muscle sciatica and pelvic joint trouble.
Imaging isn’t automatic. Uncomplicated sciatica often isn’t scanned right away. An X-ray suits a suspected fracture, especially in older adults, while an MRI suits warning signs, weakness, or pain that isn’t improving after weeks. Scans after an injury often show older wear that was there before the fall,22SpringerLink / Neuroradiology. Whiplash-associated injuries in medicolegal contexts: a review of imaging findings and a pictorial essay so comparing with earlier scans helps tell fall damage from old changes.23SpringerLink / Neuroradiology. Whiplash-associated injuries in medicolegal contexts: a review of imaging findings and a pictorial essay An MRI finding of disc wear doesn’t by itself prove the fall caused it.
To prepare, be ready to describe the fall step by step, including what part of your body hit first and whether you could get up unaided. If you’ve had back scans or X-rays before, bring the reports or tell the clinician where they were done. Wear clothes that are easy to move in, since you’ll be asked to walk, bend, and lie down.
Treatment Options and What Works
For new sciatica, staying active and understanding that it usually improves are recommended.24PubMed Central. Diagnosis and treatment of sciatica Anti-inflammatory pain relievers like ibuprofen give a small, short-term benefit.25PubMed Central. Diagnosis and treatment of sciatica Keep moving within comfort rather than resting in bed. Short walks several times a day beat long sitting. Ice early and then heat can ease muscle spasm, and changing positions often, with a pillow under or between your knees, takes pressure off.
Take ibuprofen with food, at the lowest dose that helps, for the shortest time you need. People with ulcers, kidney disease, heart disease, high blood pressure, or on blood thinners should ask a pharmacist or doctor first. Acetaminophen is an alternative some people use when ibuprofen isn’t suitable, though evidence for either is modest.
Physical therapy usually starts once the worst pain settles. A therapist can tailor exercises to a disc, buttock-muscle or pelvic joint cause. Gentle nerve and core exercises help you return to activity, and therapy also teaches safe lifting and bending.
For sciatica from a herniated disc, an epidural steroid injection, a shot near the nerve, eases pain for up to about 3 to 6 months.26PubMed Central. Efficacy of epidural steroid injection in the treatment of sciatica secondary to lumbar disc herniation: a systematic review and meta-analysis The relief fades longer term, and nerve function doesn’t clearly improve.27PubMed Central. Efficacy of epidural steroid injection in the treatment of sciatica secondary to lumbar disc herniation: a systematic review and meta-analysis People who get the spinal steroid shots tend to need fewer opioid pain medicines.28PubMed Central. Efficacy of epidural steroid injection in the treatment of sciatica secondary to lumbar disc herniation: a systematic review and meta-analysis
Surgeons can remove the part of the disc or bone spur pressing on the nerve.29Mayo Clinic. Sciatica – Diagnosis and treatment But surgery is usually reserved for severe weakness, bladder or bowel loss, or pain that won’t improve with other care.30Mayo Clinic. Sciatica – Diagnosis and treatment
How Long Recovery Usually Takes
Most people with sciatica recover on their own over time.31PubMed Central. Diagnosis and treatment of sciatica Over two years, disability from sciatica usually drops substantially.32PubMed Central. Pain-related fear and functional recovery in sciatica: results from a 2-year observational study Some people stay the same or get worse, though, and their fear of pain-triggering movement stays as high as at the start.33PubMed Central. Pain-related fear and functional recovery in sciatica: results from a 2-year observational study That lingering fear can hold back recovery, so it’s worth addressing.
Avoiding all movement tends to stiffen muscles and prolong pain, while a gradual return to activities rebuilds confidence. A therapist can grade activities step by step.
Leg pain often eases first, with the back and buttock aches fading later. Pain retreating from the foot up toward the buttock is often a good sign that the nerve irritation is settling. Progress is usually uneven, with good days and flare-ups, so judge by the trend across weeks rather than day to day. Numbness can linger after the pain has gone, and that alone doesn’t mean things are getting worse, though new or spreading numbness should be checked.
Some situations call for a recheck. No improvement after about six weeks warrants a follow-up, new numbness or weakness needs earlier review, and pain that keeps you from sleep or work should be reassessed.
Documenting the Fall and Preventing Another One
In injury claims, telling fall damage from earlier wear is a key question, and earlier scans, if you have them, can be essential evidence.34SpringerLink / Neuroradiology. Whiplash-associated injuries in medicolegal contexts: a review of imaging findings and a pictorial essay Tell your doctor about the fall at your first visit and keep copies of your records.
Write down the date, place and how you landed. Take photos of the hazard, such as a wet floor or broken step, note witness names and any incident report, and keep a symptom diary noting when leg pain started. Ask for copies of visit notes, imaging reports, and discharge papers, and keep them together in one folder or phone album. Note who treated you and on what date, since claims often depend on a clear timeline. If you had back pain before the fall, say so honestly, because that is more credible than concealment. This is general information rather than legal advice, so for a formal claim ask a lawyer what is needed.
To prevent another fall, secure rails reduce how many older adults fall at home and how often.35Taylor & Francis Online (Assistive Technology). The influence of home modifications on falls in community-dwelling older adults: A systematic review Other home changes combined showed mixed results.36Taylor & Francis Online (Assistive Technology).

Other steps are good lighting on stairs and night paths, and supportive, non-slip footwear. Ask a doctor about medicines that cause dizziness. If you’re older and cracked a vertebra, ask about bone density testing.
