[|Human|] 5 year old has rash on lower back and buttocks that is red, dry and warm to touch. It looks exactly like a sunburn. Had fever when rash started up to 104 and congestion/runny nose/cough. Fever now gone. Been treating with benadryl and cortizone cream. After 3 days no change. Now he is refusing to walk but can t express any specific pain . Will only stand on tip toe. Dr baffled...any ideas what this could be?
[|AI|]  Hi...by what you quote it looks like a toxic urticaria or a viral induced allergic rash. But, skin conditions are best diagnosed only after seeing directly. I suggest you to upload photographs of the same on this website, so that I can guide you scientifically.  Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
