About a month ago I woke up with mosquito bite looking bumps all over my knees and elbows. It itched like crazy. I took some Benedryl and within half an hour it went away. For the next few days, whenever I woke up, the bumps were back. Some days were worse, some days not so bad. And sometimes it would spread a little down my arms, or spread to my feet. Well it stopped for a while, and then I would randomly get it again. Well the past few days have been bad. I would wake up and it wouldn't be there. But after about an hour of being awake, I would get them on my knees, all the way up my legs, sometimes on my butt. I dont have any Benedryl now, so it would stay most of the day, but be gone by the time I went to bed. I dont know if its an allergic reaction to something Im doing, or what. Does anyone have any advice?
