Hi, Three weeks ago I had hives appear on my body - I don t know whether it was Nutella which caused it as I got the hives after eating it but not straight away. I went to the walk in clinic on that day as my face was all swollen and they prescribed me fexofenadine. The next day I managed to get an appointment with my own doctor as my lips were swollen but I could still breathe. My doctor put me on a 5 day short course of prednisone which helped the hives to disappear. It finished two weeks ago on a Sunday. Then a few days later the hives appeared again all over my body and I went to see my doctor again who prescribed me another short course of prednisone but this time for 7 days and sent an urgent referral to the allergy clinic. It worked and the hives disappeared, my course had finished last Tuesday and again on Wednesday evening the hives appeared. I went to the doctor today and they have given me ranitidine to take and am still waiting for the appointment at the allergy clinic. I also have been extremely tired for 3 years now and diagnosed with Chronic Fatigue Syndrome. I ve had numerous blood test which also checks for thyroid level but they have come back normal. The symptoms I suffer is the same for hypothyroidism.
