Well I tried the urticaria.Com site and received the homeopathic meds which started taking. The thing is that I also started exercising around the same time and begin eliminating alot of things from my diet. My advice to you try to avoid unnecessary preservatives (aka sodium benzoate,etc). I also gave up diet coke which has aspartme in it which is a huge a allergen for some cu sufferers. I carefully look at ingredients and try to avoid stuff that has preservatives in it. Try to eat organic bread, yogurt, milk, etc...I'm telling u I used to think it was all pointless but i've learned from experience it helps! Okay the first couple of weeks of exercising was hell but now my cu is so much better! I used to not be able to sweat and now I do w/out rash! I think the homeopathic meds had some impact but my boyfriend seems to think it was only the exercise and diet modifications that helped my condition. One more thing I have to add for the smokers out there, I hate to say it but cigarettes make it worse. I smoke here and there and I can tell if i've smoked that day or the night before, a mild rash will show up during a workout or stressful warm situation! I know its hard but try to avoid the cigarettes. So take home message from this post, start exercising, avoid preservatives and avoid cigs! Okay well if anyone has any additional questions please let me know via private message.
