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.
