Ive been waking up with red itchy bumps for the past two days now i get them every year and every time they get really bad i go to the hospital and they always say the same thing allergies or allergic reaction but i know ot cant be that cause they come and go through out the day even when i havent ate or drank anything i normally get them during the heat the most and every now and then during winter but not as bad sometimes i get them just on my arms or my legs and when its really bad my whole body even my ears
