Welcome Wolf-
You will find folks active once truly healed according to the doc's restrictions, rehabilitation, direction. KZL, for instance, just rounded the sixth month anniv of her SCS and this past weekend writes of playing her first round of golf since before. Doc agreed with her. She is tough. Went for 9, I guess, then remained for 18.
Look around, you will find others who have been active. I am only 1 month out from surgery, have the appt with my surgeon tomorrow, am nearly weaned from the pre-existing pain management meds, and HOPE to be able to return to some of my pre-injury life of 5 1/2 years ago where I was an avid mountain biker, alpine skier, hunter, hiker, and DANCED with my wife. So, hope is in charge here.
Take it easy according to your doc's instructions. Failing in that can result in messing up the works.
Good luck,
