<s>[INST] My grandson 2 and half year suddenly started scratching his skin and being uncomfortable while sleeping,. It s 4am in my country. When I checked he has bumpy rashes on his thighs, buttocks and wrists. They are big and small all sizes. They are very itchy. I have given him 1.5 teaspoon of Tandigyl syrup. I and my husband are sleeping with him in between us in the bed. I m 54 and had a complete hysterectomy 3months back. Please advise what is it and what to do? [/INST] Hi... Thank you for consulting in Chat Doctor. It could be any viral erythematous illness. But as you quote them as itchy blisters - the possibilities are Hand Foot Mouth disease/ Chicken pox/ any other trivial viral exanthem. 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>
