<s>[INST] Hi my child has had a rash that started in her diaper are and has spread all over the body we were given an alergy med by her Dr. But now the rasChatDoctores and goes every couple of hours is hot in the rash and slightly purple and bumbumpy what can we use to calm it. [/INST] Hi...by what you quote this looks like urticaria or a simple skin allergy. You can use HY Chat Doctor.  Most important thing to be remembered is that it has a propensity to recur (called as second crop) within 10-14 days. If this happens, you can start using the same medicine, but I suggest you get the kid evaluated with your pediatrician. 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. </s>
