I am 52, disabled female, who for the past few years have having difficulty in walking. My entire right leg feels heavy and stiff. My right thigh has been constantly in pain and the nerves in the thigh seem like they are asleep all of the time. Last night I thought was not going to make it home, because of all of the issues I am having with right leg. At night my right foot and hamstring have tendencies to cramp and it affects my sleeping.
