Re: Bumpy red rash, itchy at night...?
Huh. That REALLY looks like contact dermatitis. In fact, if you lived in North America, I'd guess poison ivy, but it's not normally found in Europe.
You might do better with a hydrocortisone (steroid) based cream, rather than Eurax. Eurax is good for scabies, but the medicine that treats scabies can actually make some other rashes worse, if your skin is very sensitive.
Believe it or not, it could be caused by contact with outdoor pollens, although it's more likely from something else.
