<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi I have came out in a very severe rash all over my chest and stomach very red and has little white lumps I was just wondering if you could advise me whether or not I should seek hospital treatment as this appeared on Sunday evening and is rapidly getting angrier  <response>: 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 liketo name a few infectionsbacterial, 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 ovacyst, 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 wont affect your alertness level.a topical soothing lotion like calamine would help you symptomatically. If your Urticaria still doesnt get better you might require a short course of oral steroids. Take care
