Having inner thigh pain feels like a pulled muscle?

Inner thigh pain. Inner thigh pain most commonly represents a sprain or strain of a muscle. "inner" (medically termed 'medial') thigh pain usually indicates an adductor muscle strain, or tenderness where the muscles insert on to the bone. The most common cause is an overuse injury, like bicycling too hard too long, etc. Other causes could include a hernia, a blood clot, a stress fracture of the pelvic bone, etc.
