He's had it for over two weeks and its seems to be getting worse. Saw Doctor over a week ago and she said it was viral. He's not been particularly unwell, just cold like symptoms and a mild fever. Pharmacist said it was heat rash so have been bombarding him with piriton, which has helped him sleep (deep joy) but not helped the rash.
The rash is small pink bumps which are all over his left side, left arm and left leg. They are especially bad in his armpit (they've sort of 'joined up' into one big patch). They have now moved to his right side but not as bad yet. There is nothing on his face.
Any suggestions of what it could be and what I can do to help? It has now started to itch.
