[|Human|] My son has been getting a rash periodically when we take him to the doctor with it they think it is viral. But he keeps getting them. I just cant see a virus lasting for years off and on. It doesnt flake, puss, or create any pimples. It is only on his face and it will spread all over his face. What could this be
[|AI|]  Hi and welcome to ChatDoctorGiven that the rash is periodic, it is more in favor of an allergy. It could be atomic dermatitis, basically allergic causing rashes over the face, in the creases and also other body folds. Did he have similar complaints from a very young age? It could be an allergy which increases with weather changes, dust, exposure to sun, certain plants, animals etc. Also, certain foods like nuts, seafood, processed foods, etc. You will need to keep a track of when exactly the rashes come up and if there is a common cause each time. Allergies generally reduce as the child grows, but repeated exposure to the cause can make it recur often. Use a mild sunscreen when outside. When rashes appear, apply a demonize cream on the face for 5- 7 days till rash subsides, no longer. Use an antihistamine like HY Chat Doctor. To confirm you can consult a dermatologist and run tests to check allergy levels in blood, also skin tests for possible causes. Hope this helps.
