SWIM's average prescribed dose of dexedrine is 30 mg/day but over the past months that I have been prescribed it he's noticed that his lungs are begining to hurt and feel sore on the comedown. Sometimes the annoying pain kind of attaches itself to his arm in a wierd way. I know that bronchodialation occurs and is wondering if the pain is a result of that. I have done lots of research but can't find anything conclusive. SWIM hopes it's not lung scaring and should be careful if his left arm hurts but he's in shape and knows his body and is used to stimulants. Does anybody have some insight?
