Tailbone pain is usually caused by a bruise, strain, or abnormal movement of the coccyx, the small triangular bone at the very bottom of your spine. Most cases resolve on their own within a few weeks to a few months. Women are about five times more likely than men to develop it, largely because of differences in pelvic anatomy and the added risk from childbirth. While it’s rarely serious, tailbone pain can make sitting, standing up, and even going to the bathroom genuinely miserable until it heals.
What Causes Tailbone Pain
The most common trigger is direct trauma: a hard fall onto your backside, a slip on ice, or a hit during contact sports. The impact can bruise the coccyx, partially dislocate it, or in some cases fracture it. You don’t need a dramatic injury, though. Repetitive low-grade stress, like long hours on a hard seat or cycling, can produce the same result over time by creating small amounts of damage that accumulate.
Childbirth is another well-documented cause. The baby’s head passes close to the coccyx during delivery and can push it out of alignment or even fracture it. Some women develop tailbone pain during pregnancy itself, as hormonal changes loosen the ligaments around the pelvis.
Body weight plays a role too. A BMI above roughly 27 in women or 29 in men increases the risk for both injury-related and non-injury tailbone pain. The reason is mechanical: when you sit, extra weight limits how much your pelvis can rotate, forcing more pressure directly onto the tip of the coccyx. On the other end, being very lean can also be a problem because there’s less padding between the bone and whatever you’re sitting on.
In a fair number of cases, no clear cause is ever identified. The pain simply appears, often after prolonged sitting or a minor event the person doesn’t remember.
What It Feels Like
The hallmark symptom is a deep ache or sharp sting right at the base of your spine, between the top of your buttocks. It tends to be worst in two specific moments: sitting for an extended period, and the transition from sitting to standing. That sit-to-stand flare is one of the most reliable markers of tailbone-related pain versus pain coming from somewhere else in your lower back or pelvis.
Other common triggers include bowel movements (bearing down puts direct pressure on the coccyx), sexual intercourse, and leaning back in a chair. Some people notice the pain during exercise or even just bending over. Tenderness when you press directly on the tailbone area is typical.
Conditions That Can Mimic Tailbone Pain
Not everything that hurts near the tailbone is a coccyx problem. A pilonidal cyst, an unusual pocket in the skin near the top of the buttocks crease, can feel like tailbone pain but is actually a skin condition. If the cyst becomes infected, you’ll notice swelling, warmth, redness, and sometimes pus draining from a small pit. This needs medical treatment, not cushion adjustments.
Rarely, persistent tailbone pain can signal something more concerning, like a tumor at the base of the spine. Pain that worsens at night, doesn’t improve with position changes, or comes with unexplained weight loss or fever warrants prompt medical attention. These cases are uncommon, but they’re the reason ongoing pain that doesn’t follow the typical healing pattern shouldn’t be ignored.
How It’s Diagnosed
Tailbone pain is primarily a clinical diagnosis, meaning your doctor identifies it based on your symptoms and a physical exam. The key finding is localized tenderness when pressing on the coccyx. In some cases, imaging is ordered. Standard X-rays can reveal fractures or dislocations, and specialized sitting-versus-standing X-rays can show whether the coccyx is moving abnormally when you change positions. MRI is typically reserved for cases where the doctor suspects infection, a mass, or another underlying condition.
What You Can Do at Home
The right cushion makes a significant difference. A cushion with a coccyx cutout, essentially a wedge or flat pad with a gap at the back, keeps pressure off the tailbone while you sit. These outperform the donut-shaped cushions that doctors have traditionally recommended, which were actually designed to relieve pressure on the genitals rather than the coccyx. Most people with tailbone pain find the cutout style more comfortable.
If you need something portable for work, travel, or social settings, a U-shaped neck pillow (the kind sold for airplane sleep) works surprisingly well as a seat cushion. It’s open in the back so it doesn’t press on the sore area, and you can bend it to adjust the fit. It’s also far less conspicuous than carrying a medical cushion into a meeting.
Beyond cushions, over-the-counter anti-inflammatory medications can help manage pain and reduce local swelling. Ice applied to the area for 15 to 20 minutes several times a day is useful in the first week or two after an injury. Warm sitz baths, where you sit in a few inches of warm water, can ease muscle tension around the coccyx. Avoid sitting on hard surfaces whenever possible, and try leaning forward slightly when you do sit to shift weight onto your thighs instead of your tailbone.
Physical Therapy for Tailbone Pain
When home measures aren’t enough, physical therapy focused on the pelvic floor can be effective. The muscles of the pelvic floor attach near the coccyx, and when they’re tight or in spasm, they can pull on the bone and perpetuate pain. A pelvic floor therapist works on relaxing and stretching these muscles, particularly the levator ani, which forms a sling across the base of the pelvis.
In some cases, therapists use internal (intrarectal) techniques to manually manipulate the coccyx back toward its normal position or to release tight muscles that can’t be reached externally. This approach has shown good results for patients whose coccyx is stiff or slightly misaligned, especially when symptoms have been present for less than a year. A typical course involves a handful of sessions over a few weeks.
Injections and Nerve Blocks
For pain that persists despite conservative treatment, an injection near the coccyx can provide relief. The most targeted option is a ganglion impar block, which involves injecting a local anesthetic near a small nerve cluster that sits just in front of the coccyx. This block delivers a significant reduction in pain for many patients. Sometimes a steroid is added to the injection to extend the benefit. The anesthetic works almost immediately, while the steroid’s anti-inflammatory effects build over days to weeks as it reduces swelling and calms irritated tissue.
When Surgery Becomes an Option
Surgery to remove part or all of the coccyx (coccygectomy) is reserved for chronic cases that haven’t responded to months of other treatments. It’s not a first-line option, but when it’s appropriate, the outcomes are encouraging. A review of over 700 patients found that 84% reported good to excellent results after the procedure.
The main risk is wound infection, which occurs in about 10% of cases. The surgical site sits in an area that’s difficult to keep clean and dry, which accounts for the relatively high infection rate compared to other orthopedic procedures. Other complications like blood collection at the wound site or delayed healing are less common. The overall complication rate across published studies is around 13%, and reoperation is rare, occurring in less than 1% of cases.
How Long Recovery Takes
Most tailbone pain resolves within a few weeks to a few months with basic home care. The wide range reflects the severity of the underlying cause: a mild bruise might feel better in two to three weeks, while a fracture or dislocation can take considerably longer. Pain that persists beyond this window is classified as chronic coccydynia and typically benefits from the more targeted treatments described above, starting with physical therapy or injections before considering surgery.
During recovery, the biggest challenge for most people is simply getting through the workday. If your job involves prolonged sitting, a proper cushion and periodic standing breaks are the two changes that make the most practical difference. Recovery doesn’t require bed rest, and staying moderately active generally helps more than staying still.
