My 21 month Old son has suddenly come out in a really blotchy rash, I thought it was chicken pox at first as they started out as spots, now they are mostly massive red blotches, as though he has been hit with something or scalded.. it is not on his face, just his torso down? He also seems well in himself apart from last night he was screaming and crying for about 2 hours, but today he is fine.
Hi... Thank you for consulting in Chat Doctor. By what you quote it should be an 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. 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.
