My husband overdosed on adderall and now has shooting pain down his left arm almost constantly. He is angry all the time and blows up over everything. He also has occasional chest pain. I have read that adderall can drop the levels of serotonin and dopamine in the brain and can also cause this pain in his arm.He has since stopped taking the adderall but the pain has only increased. Is there anything he can do to ease the pain or are these things related to a possible underlying problem?
