<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I am having allergy or I think its allergy. It appears mostly at night. I get the indication when I feel something is stuck in my oesophagus and after that I feel intense pain in my chest. Earlier my lips used to get swollen which has reduced now. Then very big patches would appear in my whole body and the itching starts. I had visited a doctor and he prescribed different types of tablets after each visits but of no use. i also did blood test but he could not figure out the cause. At last he gave me a tablet named atarax. Now whenever I feel like I am about to get the allergy, I take one tab at night which stops allergy for the next 2 to 3 days. Should I continue to take this tablet the way I am taking now?  <response>: Hello. Thank you for asking at Chat Doctor. I went through your history and would like to make following suggestions to you:1. Regarding your esophageal symptoms, personally I would suggest you to seek a gastroenterologist opinion and get upper Miscopy endoscopy done, if possible.2. If it is not possible, I would prescribe you a proton pump inhibitor Chat Doctor. If it improves your symptoms, you may need to take it for even longer time.3. Please try to correlate your allergy symptoms with your food intake. Common foods causing allergies are peanut, milk, soy, egg, wheat, tree nuts, fish shell fish, some fruits vegetables. Especially if you are getting symptoms within 1-2 hours of consumption of any food, it is highly likely that you may be allergic to that particular food.4. If some particular foods are suspected, allergy testing could be done to confirm.5. For symptoms of itchy patches hives and lip swelling angioedema, Atari HY
