Clear Blisters On My Hands

[AmelaL]

Hello!

Ever since I was a kid I have suffered from a heat rash (sudamina). The clear blisters would only appear when I feel overheated from the weather, usually in the summer. I used to get the clear blisters all over my body, but face. Anyway, over the years this has decreased to just legs and arms.
However, about couple of  years ago I started getting clear/flesh colored bumps on my left hand. Not itchy, not painful, not burning, not scaly. Nothing, just there. I thought it was sudamina. I started scratching them. I noticed that the blister would pop and a clear liquid would come out. No smell, no pain. But, the spots would get red and then they turn brown. How do I get rid of the unsightly look of this, besides stopping to scratch the blisters? Any OTC lotions you would recommend? Thanks.
