inner thigh pain

I suffer from pain in the inner thigh midway between the knee and the groin.
The pain is brought on most severely when I sneeze. In addition after exercise if I go into a cold environment the inner thigh muscles go into spasm however gradually clear after about 10 minutes. Any ideas?

Treating Inner Thigh Pain and Injury
A groin (adductor muscle) strain is similar to any other type of muscle strain, but it occurs when the muscles of the inner thigh (the adductors) are stretched beyond their limits. This can result in small muscle tears that cause pain and swelling. The groin muscles include the adductor magnus, adductor longus, adductor brevis, pectineus, and gracilis.

The adductors are fan-like muscles in the upper thigh that pull the legs together when they contract. They also help stabilize the hip joint. The adductors attach from the pelvis to the femur (thigh bone).

The most common cause of groin pain is a muscle strain that causes localized pain in the inner thigh, or groin.

If u feel pain on sneezing, it might be that you're suffering from sportsman hernia. Better to seek an advice from a physiotherapist!
