44/m.

About 10 days ago I felt an odd itch on my back. I didn't think much of it. 4 days ago I felt some pain and looked in the mirror and one of my long time moles (about 5-6mm) was red, swollen, and itchy.

I went to urgent care. The doctor said it may be an infection but he didn't think it looked like melanoma but I should still see the derm.

I don't know how it could be infected. I do not touch it ever so I couldn't have scratched it.

My question is, if I'm already having a reaction is it likely melanoma? And would the reaction mean that it is further along? I've obviously googled and then I didn't sleep at all last night. I'm trying to get an appointment with my derm but they usually take a lot of time.

Any advice is appreciated.
