In the last three days my chest, neck, back and legs have been quite itchy. It comes up quite red and tiny pimples or bumps come up. After a while it will calm down and then another patch will start up.
First I thought it was some sunburn that I got a few days ago but since I did not get burnt on my back and legs then it cannot be that I don't think.
I get hayfever and it is summer at the moment, could sudden changes in temperature cause it? Also, every summer I lose a bit of head hair (for about three or so weeks I shed more hair than usual for some reason) and thought maybe my skin was being irritated by my hair.
It is annoying especcially at night, because it is hard to settle down to sleep because it is uncomfortable.
What could be causing it?
