HAVE LEG CRAMPS, PAIN IN CALVES OF BOTH LEGS, WEAK LEGS, AND BELIEVE MY CIRCULATION IS POOR IN BOTH LEGS....WHAT MAY BE THE CAUSE/PROBLEM, AND COULD DIABETES BE CAUING THIS CONDITION? WOULD COMPRESSION STOCKINGS HELP MY PAIN AND CIRCULATION LEG PROBLEMS? HOW SERIOUS IS THIS MATTER, AND WHAT ELSE CAN I DO, I.E., WHAT TYPE OF DOCTOR SHOULD I SEE?
