I have had these small bumps on the back sides of my hands for about 5 years now. They itch, not constantly, mostly when it is hot. they are not red they are the same color as my skin and some kinda white looking. my skin is pinkish around the area, but not bad, I believe it is from the itching. There are about 100 of these small irritating bumps. when I first noticed it about 5 years ago, I thought something had jus bit me a bunch of times, but I had it the whole summer. when it started to cool down it went away, it was like that for the first two years, went away when it was cold, came back when it was hot. Now it never goes away, it itches more in the heat, and seems to be irritated be heat. whatever this is, it is not contagious, My husband and children have not gotten it. does anyone have any ideas on what this can be?
