The symptoms described suggest the presence of piriformis syndrome, which occurs when the piriformis muscle in the buttock spasms and compresses the sciatic nerve. This can cause pain in the hip, buttock, and down the leg, as well as foot and leg rotation. The other muscles listed are not typically involved in these symptoms.
