[|Human|] hello, My son started about a year ago getting this redness on the backs of his hands and the tops of his feet with some welts. I have sone all the questions like what he touched ate drank if it was after a shower etc. Nothing It just appears and spreads and will be there for about a hour or so and will go away He is 15 and has autism. this has been going on for a couple of years One time it was all over his back and stomach I took pictures It seems kind of pointless to take him to the doctor when I walk in with a kid with no rash can you advise
[|AI|]  Hi... By what you quote it should be an urticaria or a simple skin allergy.  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. A simple suggestion is to carry an image of the welts in your cell phone when you go to your doctor next time. 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.
