Good luck to ya on getting that cleared up.
Like you said to everyone DON'T WAIT. I had a heart operation 7-8 years ago. Right after that operation my skin doctor "found a spot" and said it had to come out now. Since I was on blood thinners when they found it, I wanted to wait the 3 months until I came off of them.
Doctor said "No Way" we're removing it next week it can't wait. He said had I waited the 3 months to get off the blood thinners the problem & surgery would have went from simple to complicated
