About 5 years ago small red bumps began to appear on my arms and legs. They vary in size from 2 mm to 5 or 6 mm. Now they appear any where on my body except my face. If I leave them alone they dry up and flake off in 2 or 3 weeks. If I pick at one with my fingernail the "lid" lifts up and it's raw underneath.Sometime they bleed slightly.Eventually they heal and dissappear. I've been to a dermatoligist and he said it wasn't a skin problem. He said it could be systemic. In other words caused from something in my blood. Has anybody ever heard of anything like this? It's really getting old.
