I've been having some crazy symptoms since I began brewing beer a few months ago.   About a week ago I suspected it might be the beer, so I cracked one open (a honey larger) and drank it slowly to watch for symptoms.  About 30 minutes after I finished it, my chest started tightening causing me to cough a lot.  Felt sort of like bronchitis.  I also got very tired and went to bed.  The following morning I had a dry red rash with blisters on the back of my hands and a very bad headache!  I only had 1 beer.  I started thinking back to the other days I had the same symptoms and they all coincided with drinking beers that I made.   No one else that drank my beer had any reaction.  Since I never had a reaction with a commercial beer that I can remember, I'm thinking it's the live yeast.  I've brewed oatmeal stout, honey lager, oktoberfest and a hoppy wheat.  I can't pinpoint if one is causing more of a reaction than another and I don't want to play detective.  The symptoms seem to get worse each time.  Luckily I got an appt with an allergist.  I will be meeting with him later today.  I hope he can pinpoint what is specifically causing this.  If it's my homebrew, I'm gonna be devasted! :angeryell  
Has anyone else experienced something similar to this?
