Mole Removal + Crusty Q&A

I was removing my pants and I kind of slipped into it then I felt a sharp pain and it was already bleeding. I peeled it off a bit.

I think I got red moles could estrogen dominance may be the cause. Have hypothyroidism. Is there anything to worry about those moles? Also the skin on arm feels rashy. 2 moles may be crusted

Have had a normal round raised brown mole on my arm for many years approx 6mm diameter. Recently the surface has become crusty like a scab, now has wart like appearance. It has not grown and does not itch or hurt. GP says doesn't think anything sinister but have been referred to dermatology. Can a normal raised mole crust over like this without being malignant?

I woke up one morning to find that I maybe have scratched my mole and maybe irritated it a bit. But over the past few days, I have noticed it has been very red, crusty, and a burning sensation every time something rubs across it or touches it. I have looked up everything and worried myself because of some of the things that have popped up and could possibly be the outcome.

I'm really nervous about this mole. At times its real and crusty. Last night it opened up and hurts. Not sure what to think?

I have a mole on my back that used to be smooth and light brown but now is crusty like a scab. After I shower and towel off it bleeds. If touch it the top crumbles off. Should I be worried?
