About a month ago i woke up with a cluster of bumps on the left side of my neck. I scratched them and the next morning there were big whelps instead of bumps and I also had one bump on each eyelid and several bumps on my hands. About a few days later the whelps went away and left my neck discolored from where the whelps were. The other bumps on my hands and eyelids went away and also left my skin discolored. I haven't regained all of the color yet but eventually I think I'll get my skin tone back. Now the same thing has happened again. This time it's on my chin. Two days ago I had this small bump on my lower chin and i picked with it because it was itching. The next morning there was a cluster of bumps in the exact spot and it was itching even worse. Today, which is the third day of this outbreak, I went to the doctor and he said it looked like the herpes virus, but I just got checked for STIs, so I don't think it's that.
I'm sure you found an answer for your question long ago, but I wanted to answer this in case it's helpful to someone else. It is possible to get herpes on the chin and neck, though you'll need to see your doctor to have it properly diagnosed. It sounds like you may be describing herpes gladitorum. One of the most common ways to contract a herpes virus like this is through contact sports that put you in direct skin-to-skin contact with someone who is infected.
It's possible to reinfect yourself, so my advice is to stop itching/picking at the bumps completely. And definitely see your doctor, who will be able to help you manage this outbreak and the itching/pain it can cause.
I hope that helps!
