Over the last couple of years, I've been getting quite a few growths that look like warts on my neck, a few months ago I got one near my armpit, I didn't think much of it until it grew and then became bigger and my bra started cutting into it. I've made a doctors appointment but I've had to wait ages so until I could go - I put a plaster on it to stop my bra cutting into it. It's now gone black and stings - wondered if anyone had any thoughts on whether it sounds like a wart and what I should do?
