For the past year i have been getting these red bumps on my hands..like on my fingers, on the back of them and between my fingers...no where else..not on my palms or anyone where esle on my body... they appear when they want to for no reason...they feel swollen when i touch them but then in a couple days they just go away..but they come when they please..i have gotten blood work and everything came out normal..my doctor says it isnt herpes either...i have to go to the dermatologist soon but does anyone know what this could be? has anyone ever had this before?
