After months of trying to work out what is wrong with DS's skin it tuns out has eczema. Cue the emollient cream, paraffin baths and steroid creams. The patches get better, flare up again, sometimes to the point of bleeding, new patches appear, it's a never ending cycle. Even when the sores are at their best they never disappear, they leave a grey/pinkish patch; before flaring up again 
This all started about 4 months ago, and he's now got patches all over his legs and on his hands and wrists. Frankly, it looks disgusting. And it has been ruling his life for months, I wouldn't say he's self conscious, he's too young for that, but he talks about them regularly; plus they're itchy!
I've been to the GP so many times I've lost faith. Would a referral to a dermatologist help? Or having him allergy tested (we have a cat)?
Help!
