My dd has had a rash now for almost weeks. It started as a few red spots around her neck and shoulders, like stinging nettle. I thought possibly allergic reaction, so did pharmacist, so I gave her loratidine antihistimine for a week. It got worse, spreading down her arms, chest, back and getting worse on shoulders. It intensely itchy, and feels rough. We have seen the GP who gave her a different antihistamine. That was two days ago and now it's redder and itchier than ever, and spreading. The rash is weeping in the worse places, and very painful now. My dd (10) is trying not to scratch but it's so hard.
We are not a family prone to allergies, eczema etc, and I've never seen a rash like this. Any ideas? Should I take her back to the GP? I'm worried it's infected now.
