Hello. Thank you for asking at HCM. I went through your history. What is something unusual is you don t have significant itching and also puffiness of eyes do not improve with antihistamines. At this point, I would suggest you to get urine examination (routine & microscopy) done & also get blood tests (serum creatinine & blood urea) done. This will help to know whether the symptoms are due to any kidney related illness. Personally I believe that consultation of a physician will be more helpful to you. Regarding your question about food allergy, it is possible, but unusual as you don t have any other symptoms of food allergy like itching, hives, abdominal pain, gastric upset, flatulence, etc. Hope this will be helpful to you. Wish you the best of the health. Regards.
