for the past few months I have had a recurring itchy reddish pink rash on the right side of my neck. I first noticed it a few months ago in early summer and it has been coming back every now and then in the same spot, nowhere else. I haven't been using any different products, wearing any irritating jewelry or clothing, or doing anything differently that I can think that would irritate it. The only thing I can think of that MIGHT be causing it is I got a mild sunburn on my neck in the early summer and a few weeks later in early July this rash appeared for a week or two, flaring up every couple of days. It hasn't shown up in a month or two except for yesterday when it seemed to appear again out of nowhere. There aren't any bumps, it is just a red patch about the length of a thumb, in an oval shape that is quite itchy and is slightly raised. Any help on what this might be would be useful! thank you!!!
