As we all know there is no real answers to anything just trial and error to what will work for you. My husband suffers terribly from chronic urticaria and when I was researching everything I found that I had to trawl through information and even pay sometimes.
I resented this as it is a terrible condition and I just wanted help. I created a page with all the information on in the hope that it will help someone and stop anyone paying for it. The link to the page is below, it doesn't cost anything and feel free to ask for further advice and add your own ideas and advice.
