Sue,
See what kind of trouble I can get into when I can't ride my bike?? I was gonna name my bike Murphy...maybe it's more accurate to call me Murphy...
And YES, this is probably happening because of lack of margarita therapy

Petra, that's always my fear. Guess it can't hurt to call - maybe the nurse will know what it is.

I can only wear my tennis shoes. I rode my trainer last night with cycling shoes. It didn't hurt while I was riding but once I took my shoes off it did.

Off to make the call - thanks!
