The solar thing is just what the doctors said. I had a lot of pressure on my chest during a hospital procedure and now it is all over my chest. That was NOT solar. I am assuming it’s due to my thin skin & being on a blood thinner. I take it due to A-fib which causes strokes. My mom died of a stroke so I am concerned naturally. My legs haven't been in the sun but I have huge dark purple marks (bruises) above my ankles. I wish there were a cure!
