Urticaria and Angiodema problems, what more can I do?

I suffer from both. Sparked off by shock when widowed. Despite taking prescription antihisthamine (1 morning 2 at night, all different names) still suffering. When angiodema kicks in and my face is swollen, it is sometimes my eye (occasionally both) my mouth - it is my lips and lower face with occasionally my cheeks too. If it is my tongue or throat I have to use 'epi pen' and get to hospital. I also have prednisnolone (steroid tablets) but with the side effects, have now piled on the weight and have become diabetic.
All this has affected my work as I cannot work when this flares up. I am at my wits end. Please advise me.

I'm afraid I don't have a magic answer so if you want advice on prescription meds don't ask me. I can sympathise, my son has terrible urticaria from certain fruits and has an epipen for allergies and it's really crap.
Sorry if it's not your thing but have you thought about doing some sort of course, maybe weekend or week that is based on healing, counselling type therapies that may help you with the emotional side of things following your partner's death? You don't say much about that except that it was a shock. Perhaps taking some time to work with the emotions involved may help your state of mind and through this your physical health. (I have no vested interest by the way) I have seen a friend change in such a positive way by giving herself the time and space and permission (!) to feel how she feels and get on with it without wallowing or equally keeping everything shut away.

I'm not saying everything physical is cured by the mind, that would be silly but I do think it is far more important than most of us think and I'm sure you'll get lots of answers about creams!

Very best wishes to you.
