Pulled or Torn Groin? How to Tell the Difference (and What to Do Next)

Written by Alex Bell, Physiotherapist & Director

TL;DR: A pulled groin is a mild strain of the adductor muscles, while a torn groin means more fibres have given way and takes longer to heal. Both cause pain on the inside of the thigh, but a torn groin usually comes with sharp pain, swelling, or trouble walking. For runners, the real risk isn't the injury itself, it's going back to training before the muscle is ready.

The quickest way to tell a pulled groin from a torn groin is how it happened and how it feels straight after. A pull tends to build as tightness or soreness that you can still run through at a reduced effort. A tear usually announces itself with a sudden sharp pain, sometimes a pop, and makes it hard to walk normally, let alone run. Getting this distinction right matters, because it changes how long you should expect to be out of training and how carefully you need to build back up.

Why Runners Get Groin Pain

The adductors, the muscles running down the inside of your thigh, work harder than most runners realise. They control your leg as it swings back toward the midline with every stride, and they're under even more load when you change direction, sprint, or run on cambered or uneven surfaces. Groin strains are more commonly associated with sports like football and hockey, but any runner who ramps up speed work, hill sessions, or weekly kilometres too quickly can load the adductors beyond what they're conditioned for.

Pulled Vs Torn: What's Actually Different

Think of the muscle fibres like an elastic band. A pulled groin is the band stretched further than it likes, uncomfortable but still largely intact. A torn groin means some of those fibres have actually given way, and in more severe cases a good portion of the muscle can tear. That's the difference between a niggle you can run through carefully and an injury that needs a real break from training.

Signs Of A Pulled Groin

A pulled groin usually feels like tightness or soreness along the inner thigh that gets worse with side-to-side movement or a change of pace. You can generally still walk normally, and most runners can still jog, even if it's not comfortable. Swelling and bruising are rare.

Signs Of A Torn Groin

A torn groin feels different from the first moment. Many runners describe a sudden, sharp pain, sometimes with a popping sensation, often during a sprint effort or a hard change of direction. Walking becomes noticeably harder, and swelling or bruising may show up around the groin or inner thigh over the following day. You might also notice your leg feels weaker when you try to bring it across your body.

What This Means For Your Training

If it's a mild pull, gentle movement, including light, pain-free jogging, is usually fine and can actually help recovery. Ice for 15 to 20 minutes can help if there's any swelling, and some runners find compression shorts or taping useful when they start easing back into sessions. A torn groin needs a different approach. Training needs to stop, or be reduced to what's genuinely pain-free, while a physio works out exactly which structure is affected, the muscle belly or the tendon, and how severe it is.

From there, rehab typically starts with pain management and gentle activation, then moves into resistance work, starting with simple isometric squeezes and building up to bands and weights. Later stages bring in the movements specific to running: change of direction, strides, and eventually full-effort sprinting. Rushing this progression, or heading straight back to speed work because a niggle feels "mostly fine," is one of the most common reasons runners end up back at square one.

How Long Until You're Back Running?

A mild pull often settles within one to two weeks of appropriate load management. A moderate tear typically needs four to six weeks before a full return to running-specific training, and severe tears can take eight to twelve weeks, sometimes longer, particularly if there's been a delay in getting it properly assessed. Reinjury is common in runners who return to full training before they've finished a structured rehab program, so building back gradually is worth the extra week or two it might cost you.

Can Physiotherapy Really Speed This Up?

Yes. A structured rehabilitation program does more than get you moving again, it's shown to reduce the chance of the injury coming back. A widely cited review agreed on clearer definitions for groin pain in athletes, which helps physios pinpoint exactly what's driving your symptoms rather than treating it as a generic strain (Weir et al., 2015). Separately, a large trial in football players found that a targeted adductor strengthening program reduced the risk of future groin problems, evidence that's just as relevant to runners loading the same muscle group (Harøy et al., 2019).

When To See A Physio

If you can't walk without pain, notice swelling or bruising, or find your groin pain keeps returning every few weeks of training, it's worth getting assessed rather than guessing. Groin pain can also come from the hip joint or lower back rather than the adductors themselves, so an accurate diagnosis makes a real difference to how quickly you recover and how confidently you can return to training.

Key Takeaways

• A pulled groin is a mild strain, sore but usually still walkable and often runnable at reduced effort.
• A torn groin involves more damaged fibres, often with sharp pain, swelling, or trouble walking.
• Recovery ranges from one to two weeks for a mild pull, up to eight to twelve weeks for a severe tear.
• Rehab should progress from pain management through strengthening to running-specific drills before a full return.
• Returning to full training too early is one of the most common causes of reinjury.
• Physiotherapy assessment helps rule out other causes of groin pain, like the hip or lower back.

FAQ

Can I keep running with a pulled groin?
Often yes, at a reduced pace and distance, as long as it stays pain-free. If sharp pain or a limp shows up, stop and get it assessed.

How do I know if it's actually torn and not just tight?
Sharp pain at the moment it happened, difficulty walking normally, and any swelling or bruising point toward a tear rather than a simple pull. When in doubt, get it checked, since guessing wrong can add weeks to your recovery.

Do I need a scan to diagnose a groin strain?
Not always. A thorough physio assessment can usually identify the injured structure and its severity. Imaging is sometimes used for more severe or unclear cases.

Why does my groin pain keep coming back every few months?
This is usually a sign the muscle wasn't fully rehabilitated, or strengthened beyond its pre-injury level, before returning to full training. A structured strengthening program is the main way to break that cycle.

Is stretching enough to fix a groin strain?
Stretching alone rarely resolves a groin strain. Strengthening the adductors, alongside a gradual return to running-specific loads, is what the evidence actually supports.
