My coworkers and my self have been had nausea, warm face with redness, burping or vomitting, and it has been going on for weeks at random. We just realized we have the same symptoms. The symptoms are not strong. Only when one of use vomited, did we realize we all had the same thing. One of my concerns was we all work at a bank and handle money all the time. Not sure if we caught something rare from the money? The only thing I could find that come close is Cellulitis, but that is very unlikely for us all to have it. Any ideas?
