ok, I have been getting these for a while now. But this time its on the top of my head and yucky and painful!!! Usually, they go away on their own. I have been alternating with peroxide and alcohol. Any thoughts

I was recently at the shore and pools this weekend. And thought it was a sunburn on my head. I also have an itchy rash on my neck.

On rebif, gabapentin, pristiq, nexium

Thanks
