<bot>: Hi. Thanks for posting your concern at ChatDoctorYou seem to be suffering from Hives OR urticaria would definitely advice that you visit a dermatologist for a proper assessment of the rash. Urticaria OR hives can occur due to various causes like(to name a few) infections(bacterial, viral, fungal), Chat Doctor.  A few cases have no underlying cause and are known as idiopathic urticaria. I would advise you to get few basic lab tests like Hologram, stool for ova/cyst, Urine routine, Chest X-ray. An oral antihistamine like Fexofenadine OR Loratadine once or twice daily for a week would be suitable. They are non-sedating and won't affect your alertness level.a topical soothing lotion like calamine would help you symptomatically. If your Urticaria still doesn't get better you might require a short course of oral steroids. Take care
