My little one was VERYpoorly last week. The doctor said that her ear was 'a bit red' so thinking it to bean ear infection,he issued Antibiotics. Forgot to add that she had 39/40 degree temp even the day! Anyway, they started to work but by day 5, a minor rash appeared. I took her straight back to the doctor, and he said, that it could be a reaction to the penicillin. Not for certain but definitely not so etching to worry. Keep up the antibiotics. Her temp went down and the rash was there but settled. On day 7 we finished the medicine. BUT...even though we finished the antibiotics, now day 9 and 10- an immense rash has appeared. Bumpy, red. On arms, legs, a little on cheek, a little on ear...looks very sore but doesn't seem to bother her at all. No temp or old etc. Back to the doctors and I asked- is it measles? Chicken pox etc? And he said No- looks like a drug reaction. Gave us Chamomile lotion. My question is do you have any experience of this? The only thing that's puzzling me is whether it could be Cows milk. It's the only thing that is new the last two weeks. But she's had it in cereal and cheese products and no reaction before??? Any advice?
