sick after swimming in lake zurich this past weekend?
Hi everyone. I'm a regular swimmer, including in the Zurichsee. Usually feel just fine. However, swam a bit longer this past Sunday and may have taken in some water, and I am now having some unusual belly cramps and diarrhea since Monday morning... nothing too bad but makes me wonder..
I know 2 other people who have been experiencing something similar after swimming in the lake in the past few days.
Anyone else here? What could this be?
