As the title says I have small purple bruises that appear on my bicep. This is the fourth time they have appeared in the same place on my bicep. They go away for a week or two then come back.
I have not done anything to knock them, or lifted anything heavy.
They are not pin prick bruises but spots the size of a rubber on the end of a pencil.
Any one have this happened to them? Any idea what it could be?
