Two months ago I forgot in all stupidity to apply sunblock to my arms whilst taking a walk along the coastline. A fresh breeze made the temperature pleasant, too pleasant to notice I had started to get sunburnt. Once I realised, it was already too late.
Over the next few days the burnt parts turnt a vivid red colour, and started to sting. After applying a cream I had gotten from the pharmacy and taking cold showers as per the advice from the clerk, the burn started to fade in about a week.
It's been one and a half months now since my sunburn has completely faded away. But on my right upper arm (the side I burnt most severely) I now have a very small, light rash consisting of very small red spots. It doesn't itch, doesn't hurt, but also doesn't go away. It is not bumpy, and can't easily be felt. I'd like to add a picture but can't quite figure out how (I'm new here).
Any ideas of what this could be? It is currently very difficult to get to a doctor's post for me, hence I'm seeking advice on here first.
