 [ Symptoms ] i have a red rash with red bumps on the backs of my hands mostly clustered around the base of my thumb and forefinger  i can not think of anything new i have come into contact with that i would be allergic to a few of the larger bumps are almost look like small scrapes but they are not they do not particularly hurt or itch i have had them for about a week i was sick with a bad cold recently they do not seem to be spreading but they also do not seem to be getting better they are contained to my hands as far as i can tell [ Disease ] hi you just need to think back it must be something you have opened using thumbs and forefingers logically these you would open something with could be a chemical fertiliser or something else that is given you this reaction see your doctor and take it from there good luck
