It feels like a minor thing, but I've had a rash on my neck for a week and I've been taking antihistamines and applying a cream to it and it's not gone down. It's a red blotchy rash, it only itches when it's been exposed to hot or cold (e.g. after showers it itches and kind of burns).
So the rash has lasted a week. Before this I would wake up with a rash on my neck, which would disappear after around an hour of being awake and I put it down to stress.
Do you think I should ring my GP or wait a bit longer? It's a minor thing. I have been feeling run down and like I'm on the brink of a cold for the last 6 weeks, and have had a bad cough too but the cough has pretty much gone now.
