[|Human|] I have been a chronic user of crystal meth for the past 20 years, four months ago all at once i had pain from butt bone all the way to my feet, long knot across the top left butt cheek, several knots stayed in calf area, heel of foot went numb and has remains numb still. knot on top butt cheek has gone away. muscle tone in calf has changed, lower extremities have started swelling as of 2-3 months ago and seems to persist all of this in left leg. right leg started a few weeks after the left and swelling is less than the left by at least 1/3 of size. emergency room Dr. has checked for everything except for liver. ekg, ultrasound of legs, cardiac stress test and extensive blood work has been done Dr. say results were good. . what the hell is wrong with me?
[|AI|]  Hi, I cannot say in your particular case without actually observing it AND swelling implies a circulatory problem. There can be damage to the vessels supplying blood to an area due to meth--especially if they were injected into. This causes numb and cold and changes in color. There can be clots in veins that permanently mess up the veins' ability to bring blood out of an area--varicose veins. And just lying around will do that. Also if there is prolonged pressure on an area, the local nerves get damaged and the area is numb in a small area. Take care. Hope I have answered your question. Let me know if I can assist you further.
