I actually purchased a used eliptical/bike today just to use it. I tried the eliptical and it hurt -way- too much, so I switched to the bike.
Sarah- No, I don't have leg or foot cramps, this came on all of a sudden and at first I thought I had stepped on something. And my regular GP diagnosed me and told me to do the stretches and if it didn't improve in a couple weeks, she would refer me to a specialist.
Staying off of it today and rolling a frozen can of peaches (poor peaches) under my foot as I did dishes really helped. So did ibuprofen and stretching my toes and feet in the tub with hot water.
Thanks for the advice ladies

It was appreciated!
