Every day at work I use 99% isopropryl alcohol and it gets on my hands in large amounts. Before I started working there I never had stomach problems, but now I am nauseated almost every day for a good period of time, I have diarrhea usually once daily and I get bad abdominal cramps and bad discomfort. Could the alcohol be causing my problems? I have been working there about 7 months and over time it seems like my problems have worsened .
