Identifying Hip Flexor Injuries

The hip flexors are the group of muscles which pull the knee upwards – they begin in the lumber region of the back and connect into the femur (thigh bone). Although injuries to these muscles are rare, it’s important to be aware of the symptoms and know what to do if you’re concerned.


Here are some of the symptoms of inflamed hip flexors. You may also have these symptoms if you’re suffering from bursitis – a specific type of inflammation which occurs where your tendons and muscles meet your bones.

  • Pain in the groin when you lift your knee up to your chest (particularly when there’s resistance).
  • Tightness in the groin.
  • Swelling in the groin.
  • The pain may disappear during your training but feel worse afterwards.

The best way to treat inflammation is to rest until the pain has gone. Applying heat to the area will also help. If you’re concerned, make sure you visit your doctor or a sports injury specialist.


Here are some of the common symptoms of ruptured hip flexors:

  • A sudden, sharp pain in the groin.
  • Weakness in the area.
  • Pain in the groin when you lift your knee up to your chest (particularly when there’s resistance).

If you think you may have ruptured your hip flexors, you should rest immediately. Applying ice and pressure to the area, and elevating your hip will also help.

You may need crutches, and during your recovery the muscle will need gradual stretching and strengthening to avoid it tightening up. If the muscle does become tight, there’s a risk it will rupture again.

Although it’s rare, if the muscle tears completely it would require surgery. Again, it’s important to visit your doctor if you’re worried.

Other conditions

Pain in the groin area is common but it’s sometimes difficult to locate the source of it. Here are some other conditions that are often mistaken for injury to the hip flexors:

  • Inflammation or rupture of the adductor muscles (the muscles which begin in the pelvic bone and connect into the femur).
  • A hernia.
  • Trapped nerves.
  • Prostatitis (inflammation of the prostate gland).
