The adductor longus can cause and contribute to pain on the outside of the front of the thigh near the hip joint. It is a prime contributor to groin pain. Movement is restricted in the hip and thigh.
The pectineus muscle can cause and contribute to pain in the fold of the leg as well as the groin and pelvis. Pain increases when walking. Sleeping with a pillow between the knees will sometimes help ease night time aching.
