My son has a rash on his chest in the form of light pink , blotchy, skin discoloration, pair with redness on his thighs which have become irritated from him scratching it, resulting in puffy raised skin. He also has had a cough and is congested. The rash appeared after his bath last night.
Hi...by what to quote I feel that this could be an Urticaria or simple skin allergy. 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. But as of now to get immediate relief, 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.
