I have recently (last two weeks or so) started developing very small bumps that look like a blister but is not. This is only on my right wrist and heel and back of my hand and a short distance up my right arm (about halfway to the elbow)
I am on numerous medications but have been for a number of years and nothing new in last few months. I am also curious as to why this would only occur on one small part of my body(?).
