<s>[INST] my baby is 12 months old he is very happy and healthy, we are in tenerife at the moment and a rash has appeared on his torso. he does have quite sesitinve skin and im not concerned it is anything serious i would just like some suggestions on what it is? it looks a little like a heat rash or prickly heat? [/INST] 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. 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. </s>
