A mild pulled groin typically heals in four to six weeks, while moderate strains take closer to two months. Severe tears, where the muscle is completely ruptured, can require several months of recovery and, in rare cases, surgery. The timeline depends largely on how badly the muscle fibers are damaged, which is categorized into three grades.
What Happens When You Pull Your Groin
A groin pull is a strain of the adductor muscles, a group of five muscles that run along your inner thigh and pull your leg inward. The adductor longus is the one injured most often. The injury usually happens when your leg is forced outward while the muscle is trying to contract in the opposite direction, such as during a quick change of direction, a wide lunge, or a kick. That tug-of-war between opposing forces tears muscle fibers.
You’ll typically feel a sharp pain in your inner thigh at the moment of injury. Depending on the severity, you might also notice swelling, tenderness when you press on the area, or bruising that develops over the next day or two.
Grade 1, 2, and 3: How Severity Affects Healing Time
Groin strains are graded on a scale from 1 to 3 based on how much of the muscle is torn.
- Grade 1 (mild): A small number of muscle fibers are stretched or torn. You’ll feel tightness and mild pain but can still walk and move your leg without much trouble. Most grade 1 strains heal within two to four weeks.
- Grade 2 (moderate): A larger portion of fibers are torn. Pain is more noticeable, especially when squeezing your legs together or lifting your knee. Expect four to eight weeks of recovery.
- Grade 3 (severe): The muscle or tendon is completely torn. You’ll likely lose the ability to squeeze your legs together at all, and the pain can be intense. These injuries take several months to heal and sometimes require surgical repair.
Re-injuries complicate things further. Straining the same muscle a second or third time often leads to a longer, more difficult recovery than the original injury. This is one reason rushing back to activity too soon is risky.
What to Do in the First 48 Hours
The first two days after a groin pull set the tone for the rest of your recovery. The standard approach is rest, ice, compression, and elevation. Avoid any movement that reproduces your pain. For moderate to severe strains, crutches for the first few days can take enough weight off the area to let the initial inflammation settle.
Ice the inner thigh for 15 to 20 minutes at a time, several times a day. A compression wrap helps limit swelling. Muscle spasms are common in the first couple of days, and ice can help with those as well. Rest from painful activities is recommended for one to three days, with continuous compression during that window.
How Rehabilitation Progresses
Recovery from a groin pull isn’t just waiting for pain to disappear. It follows a progression that rebuilds strength and flexibility in stages.
In the early phase, a physical therapist may gently move your leg and hip for you (passive range of motion) to prevent stiffness without stressing the healing tissue. As pain decreases, you’ll transition to doing stretches and movements on your own.
Strengthening comes next, starting with light resistance. This might include exercises with ankle weights or resistance bands, then progressing to weight machines and eventually functional movements like lunges and lateral slides. Stationary cycling and treadmill walking are commonly introduced as low-impact ways to rebuild endurance without overloading the adductors.
A key exercise in groin rehab is the Copenhagen adductor exercise, a side-plank variation that targets the inner thigh muscles. If you’re early in recovery, you’d start with a shortened version or simpler exercises like side-lying leg lifts. A common benchmark: once you can perform two sets of 12 side-lying hip adductions with good form, you’re generally ready to progress to resistance band work or a modified Copenhagen plank.
How to Know You’re Ready to Return to Activity
Pain disappearing at rest doesn’t mean the muscle is fully healed. Sports medicine clinicians use a series of functional tests to determine when it’s safe to return to running, cutting, and sport. Even if you’re not an athlete, these benchmarks are useful for knowing whether your groin can handle everyday demands again.
The first milestone is pain-free walking. You should be able to walk at a normal pace for about 2 kilometers (roughly 1.2 miles) on a soft surface without groin pain during the walk, afterward, or the next morning. After that, a 10-minute dynamic warm-up (leg swings, lunges, light jogging) should also be pain-free.
The squeeze test is another reliable check. Lie on your back, place a fist or rolled towel between your knees, and squeeze your legs together as hard as you can. If this produces pain or you notice your strength has dropped noticeably compared to before, the muscle isn’t ready for higher-intensity activity.
For runners and athletes, clinicians also test resisted hip adduction in a position that mimics the mid-stance phase of running. You should be able to hold the position strongly and without pain. Any discomfort during passive hip extension suggests caution with straight-line running, while pain during passive hip abduction (leg moving outward) means cutting and direction changes should wait.
When a Groin Pull Needs Medical Attention
Most groin strains heal well with rest and gradual rehab, but some situations call for a medical evaluation. See a provider if your groin pain is severe from the start, if it doesn’t improve with home treatment within a few days, or if you notice a lump or mass in your inner thigh. In men, groin pain that radiates into the testicle, pain along the lower abdomen, or blood in urine are signs of something beyond a muscle strain.
Complete tendon tears (grade 3) are uncommon but can leave a palpable lump where the torn muscle bunches up. In one documented case, a soccer player with a full adductor longus tendon tear was initially treated conservatively but still had pain with everyday activities and a visible mass after two months, ultimately requiring surgical reattachment. Clear surgical criteria for these injuries haven’t been established, so the decision is typically based on how well conservative treatment is working.
Reducing Your Risk of Re-Injury
The single biggest risk factor for a groin pull is having had one before. Strengthening the adductor muscles, particularly through exercises that load them while they’re lengthening (eccentric contractions), is the most evidence-supported way to lower that risk. The Copenhagen adductor exercise is the go-to option for both prevention and rehab, and it can be scaled from beginner to advanced versions.
Beyond targeted strengthening, a proper warm-up before activity matters. Dynamic movements that take the hips through their full range of motion, like lateral lunges and leg swings, prepare the adductors for the demands of sport. Jumping straight into sprinting or cutting without warming up is one of the most common ways people re-strain a healing groin.
