A good friend of mine had 3 back surgeries within a year. All for disk issues. One operation he had two fixed at once. I know the past couple years he was slow to get back on his machine, but this year he said his back feels 100% and he just purchased a brand new Polaris Pro-R. The issues he faced the most was failing to commit to Post-Op PT, he had trouble getting motivated to do his percribed exercises, and it didnt help he was 20 or so pound over weight. He's now working out 4-5 days a week and its looking like its going to be a good season for him.
So all n all...you need to talk with your doctor to make sure you can ride before you do. Commit to PT as required. Stay positive, you will be able to ride again. I had rotator cuff surgury last fall and pushed it a little to soon, luckly i didnt effect anything but looking back i should of hung out at camp instead of being in the tree's:wine:
