Thanks for the info on angioedema MrsD. My type of angioedema is autoimmune, which is a lot harder to treat, because my body has created antibodies to c1esterase, which means a lot of the great new meds aren't so helpful for me. But I am still struggling to work out what in the blazes sets off my swelling, so your post has given me impetus to research more on bradykinin. I had no idea about the fruit, which I eat often, or eggs. Unfortunately I am swollen almost all the time, only very rarely does the swelling dissipate these days, and it is very much GI and facial. Extremely uncomfortable and embarrassing. I never want to leave the house anymore.

But hardly being able to see suddenly is causing me some distress. For instance trying to use the computer now is so difficult. I have double vision and blurriness, so it's a real struggle to see and type. Especially considering it happened so quickly.
