Hello!
Last night I noticed what I think is a mole on my shoulder blade that has never been there before. It's in a tricky place to get a good look at it but is only small and is quite dark. I thought it might be a blood blister so tried to squeeze it (!) and a bit of blood came out but it didn't 'pop' like a blood blister. Should I see a GP or wait a while and see what happens? Thanks for any advice.
