I reread your posts and you mentioned the red bites, could it be possible that bed bugs are in your surroundings? I lived in a hotel apartment once and I had problems with red bites and itching, and sure enough the critters were there,even fleas will bite you too, if you have animals or live in a warm enviroment. There are bugs that will bite and cause skin problems and even infections in the body because they feed on the blood. maybe you should show the doc the bumps,it could be a rash or it could be hives.
