My problem is the severe leg pains (right leg only) while sitting or laying down, caused by the constant muscle cramping that I can only equate to as the worlds worse "charley horse". I do not have any pain, stiffness, or mobility problems while active or walking. I was diagnosed with PD 4 1/2 yrs. ago and have been suffering ever since with very little progression otherwise from the disease. Does anyone else suffer similiar problems ?
