There are several causes: (1) The muscles of the inner thigh are tight; (2) The muscles of the inner thigh are twisted; (3) The nerves of the muscles of the inner thigh are twisted; (4) The inner muscles are too cold because the legs are too cold during sleep; (5) A twisted lower back; (5) Twisted lower back muscles; (6) Weak lower back muscles; (7) Weak pelvic muscles.
(1) The muscles of the inner thigh are tight. One feels if the muscles are trying to “jump”. The muscles are actually trying to readjust their positions and will slip and slide. This is the cause of the “jump”.
(2) The muscles of the inner thigh are twisted. This occurred with a mechanic who was roller skating in the back yard on a cement walkway and crashed into the wooden stairs leading into the house. He slipped and fell. The thigh muscles became twisted. Acupressure and deep tissue massage were able to alleviate the condition. However, the mechanic’s brother slipped on an oil spill on the shop floor. He also twisted the thigh muscles. In this latter case, acupressure and deep tissue massage were not as helpful. He had to go to therapy and the therapist used a mechanical deep tissuevibrator on the thigh to “shake” the thigh muscles and cause the muscles to “quiver, vibrate and tremble” in order to loosen the twisted muscles.
(3) The nerves of the muscles of the inner thigh are twisted. The nerves will suddenly misfire rapidly as if electrical impulses are shooting down the thigh. This also causes the thigh muscles to jump. The causes of this misfiring by the nerves of the thigh are (4), (5), (6) and (7).
