i just want to know what the heck is causing this.lol tiny lil bumps on arms that itch at times..they kinda look like hives. had a case of them about two weeks ago but wasnt bad and they went away within a week..now theyve come back worse. i do work outside,upsdriver,but it hasnt been hot. i go to the tanning bed but maybe twice a week...my aderall is generic and have been on it for myabe lil over a month..first 5mg which did nothing then 15 which couldnt find so would take three 5mgs twice a day. now im on 20mg twice a day..so could it be the dosage or possibly something other than my medicine..
