I was just about to reply to your OP paddyann So glad to hear your update.
We are always quick to tell someone else they should see a doctor but when it comes to ourselves....
I found a tiny little pink lump at the top of my leg at the beginning of last year. I decided (with my doctors head on), that it was nothing and so left it. In fact actually no, I will tell the truth and admit that I picked at it until it bled a lot, then it seemed to dry up and almost disappear. It came back twice the size and again (with my doctors head on) I decided it was nothing and so began a cycle of picking/bleeding (I know.....).
Fast forward to this spring the little lump was quite big and eventually I thought I had better see a real qualified doctor who took one look at it and insisted that it was removed asap. I ended up having a small chunk of leg taken (sorry for the gory detail) and then worse, ended up with an infection (thank you to the wonderful GN members who persuaded me that it was infected and that I should see my GP quickly). It was indeed very infected and was high risk of Sepsis. the doctor ordered the stitches straight out (hurt like hell as it was hugely swollen) and a course of strong antibiotics. I now have have a nasty scar at the top of my leg and a horrible "feeling" that I can't describe.
Some of us are silly when it comes to putting things off.
