I am not sure if this is more of a skin cancer/rash/or general concern question so I am posting it to the general forum. On my back I have had a red spot for over a year now. It was first noticed by my mother after I had a mole removed above it. It has not gone away and today I was curious to see if it was raised or what it felt like and I vigorously rubbed it. When I did this the patch darkened, as if the rubbing was bringing more blood to the surface. Should I be worried about this spot? I have a doctors appointment on June 5th and I plan on asking, I just need to know if I should go in and be extremely worried about what is going on. Also, in a more private area of my body, I had what appeared to be a blood blister that when I picked/popped it bled profusely. Should this area also be brought up?
