If the pain is already unbearable, I would suggest you to see a doctor at this early before things get to worst. At least, they can give you some test if what's the cause of your leg and arm pain. Have you also heard of magnetic therapy? A friend of mine undergo the treatment and at the same time, he bough a magnetic bracelet to wear all the time. It really works on him especially in reducing and preventing pain from his arms, wrist and legs. You might consider that one too!
