Take heart, Karen - I had serious back surgery 16 years ago (a full fusion) and within six months I was snow-boarding, jogging and cycling, and a year later slalom waterskiing. Backs heal if you give 'em time. 16 years later my back can spend way more hours in the America's saddle than my bladder or coffee-habit can! Follow doc's orders, rest and remember that your trusty steed is waiting patiently for you, and ready when you are.
