pains are very important part in withdrawal, i have ribcage pain (maybe muscles), many have back pain, some knee, but apparently everybody has pain, maybe you have teeth pain, with time the pain diminish, or go on another place(i had back low pain, it is gone, hip pain, it is nearly gone, neck pain, it has very diminished, only costal pain spinal burning will not go away since a big while, but the other come sometime back and go away)maybe it is the same for you...
i am very sorry, i go to look TV before bed and thought i would write you a word...
