The bumps on my hands look like itty bitty blisters, not clustered. Those often pop up between
. The bumps everywhere else pop up randomly and occasionally may be in a patch. I have no pain except I will randomly get a pinching sensation from a bump and it will prompt me to itch. I have used medicated powder, medicated lotion, hydrocortisone cream, oatmeal soap, antibacterial soap, lubriderm, calamine lotion and acne treatment with sacylic acid.
