75% Done and Jock Itch?

Yes. I'm 75% done (8 out of 12 treatments) with my chemo! The 5-FU has really made me sick for the 46 hours + that I get the infusion via the pump. I don't feel better until the following Monday. Speaking of side effects - I thought I had extra chafing between my legs - near my groin. He said it looked like jock itch - (the pattern was circualar) so I'm doing a daily application of anti-jock itch cream per his instructions and its clearing up. The weird thing is - I've never had Jock itch in my life and now since I started chemo, I'm not really working out. Anyone get jock itch after starting chemo? Mike
