Rash on neck keeps on reappearing
over the last two months I keep on getting a rash that appears on the front side of my neck, usually in the centre around the Adams apple area. It doesn't have a texture to it, but is a pinkish colour and sometimes can get slightly itchy. I don't believe this is to do with shaving, as I don't shave that area. The rash lasts a day or two, then comes back a in a couple of days, usually in a different part of the neck.
I'm confused as to why this is happening, my diet hasn't changed. The only thing I can think of is blood flow around the neck. As lately I've been doing lots of push-up, like 200-300 a day, and this could possibly put a strain on blood flow to the neck. Also just before, I was sitting down on the sofa reading a book for an hour, got up and noticed a new red rash on my neck. Now when reading the book my neck wasn't in a straight position, but bent over slightly to read the book.
I'm going to see a doctor soon, but anybody have an thoughts on this.
