I have had four allergic reactions in 15 days, plus a similar one a year ago. My lips and throat swell, I itch all over and get blotches. I have had anti-histamines but they don't seem to work that well, three times I had to go to the doctor for an injection, and today my doctor has given me a 5 day course of steroids. I just can't think what I could possibly be allergic to, especially as the last four times (a) in UK at home (b) in the air in flight between Istanbul and Yemen (c) in Yemen and (4) back in UK, all different environments with completely different foods, different soaps, different people about me. And the first one last year was in Dubai. So all with different foods, environments, etc. Has anyone else had anything like this?
