ive been taking DNP for 13 days now. ive been taking 50mg of benedryl ever night. but today at 11am my knuckels started itching. around 12 they were swollen. and by 1pm i had hives on my hands, elbows, side, legs, and feet. this shit itched so bad i went to the emergeny room and they gave me some stuff to take. hell my hands were so swollen i couldnt make a fist. so has anyone else had this from DNP before or is it from something else? any help would be greatly appreciated.
