If I inhale any amount of the dust or am too close to it when it fumes up, I will have acute hives well up individually and in clusters as soon as within the hour. They progress over the next 2 weeks to covering 80% of the trunk of my body. The itching is UNBELIEVABLY intense, as is the headache and muscle discomfort. Whether related ot not, we don't know, but the first time it happened, about 2 week into it I started feeling very bad. I was having chest pains and shortness of breath. I went to the chest pain center and was found to be in Atrial Fibrilation. After about 30 hours of IV meds not stopping it, they shocked my heart twice. This was not fun.
Antihistamines are almost useless unless in huge doses (2-3 each per day of 180mg Allegra). It was not going away on its own and took an Aristocort steroid shot to knock it out. After it was gone, I spent three day either turning or being around turning with no signs of an outbreak. On the 4th day I turned 2 pens and finished with CA. Within an hour or two I knew it was the source of the reaction. Within 5 days I had 50% of the trunk of my body and legs covered again. Another Aristocort shot and 2 - 3mm biopsies. The spots are pretty much gone (3-4 per day that fade quickly) and I am STAYING AWAY FROM CA.
Every person is different, this is just the way it hit ME. I've never been allergic to anything in my life. Now, I can't so much as have a bandaid on a cut without the entire glue area welting up.
Hope this helps someone.
