Apparently it goes away on its own?
My front and back are covered, covered with very itchy red patches. Initially I was gutted because they appeared shortly after we brought our new pet rats home but then DH remembered that he'd spotted a patch on my back on Boxing day before we even got the rats. So I've done some googling and what I have fits exactly with this diagnosis due to the 'herald patch' that arrived first; pics look the same etc. I've had it 5/6 weeks and it says it will go in 12. There's no real treatment and not contagious. I don't feel ill, I just look horrendous and spend a great deal of time scratching! Shall I wait and see if it goes or go to the GP to get it confirmed?
