adderall is a powerful stimulant the same as methamphetamines/speed -- and can most-definitely cause anxiety reaction and agitation. it does not typically cause back pain etc. so other sources need to be medically-investigated. your doctor may need to try you on a different medication for your add or whatever reason you are taking the adderall. <link>
adderall causing symptoms or anxiety? . when using i get no feeling of concentration. left lower side abdomen above hip level has dull pain and feel twitches every once in a while accompanied by lower back pain/heaviness. whenever i take adderall i can't focus like i used to instead i spend hours searching for what could be wrong with me. i am not sure if the adderall is causing me to experience anxiety that is making my mind experience "ghost" symptoms or if the back pain is causing abdominal pain from constant poor posture. . .
