Hi, you will find that your restrictions vary depending on the complexity of your case and your doctors personal preferences. Some doctors are more strict/lax than others.
A good example is my doctors said 6 weeks before driving and the previous poster said they were allowed to drive at 10 days. That is a huge difference.
As far as fishing, I would think at least 12 weeks before you could comfortably cast your line. That is a pretty big stretch in my opinon but of course I am simply another spinal patient and the best resource to get your case appropriate answer is your surgeon.
Good luck and remeraber we are here for you.
