Hi Steve,
I had my surgery 12/2007. After a medical clearance from Dr. Barker in February 2008, and a commitment to wear a helmet with sports like cycling and downhill skiing, I was supposedly ready to get up and start exercising again. It was definitely one step at a time for me...I also had headaches that would creep into my exercise routines. Of recent, I have not had any headaches, a true relief..Should I do any activity that requires a lift or strain, I get a teaser, but by stopping the activity, I recover in a few minutes, usually less than 10. My first activity post op was downhill skiing, definitely green trails, no black diamonds. I had a season pass that was purchased in August of 2007 so I couldn't bear not getting out a few times. Certainly a challenge, but far easier to do that, than walk! Hard to explain to friends and family, but walking was the hardest at the start. Gradually over the last 2 years I began to get stronger and have a more dependable endurance for nearly all my recreational fun and no headaches. My last bad headache was in May 2009 and only a few teasers since then. What I do notice is that I must maintain my fluids with my sports. If my fluids get low, it is almost a sure way to a headache. I also have to listen to my body and pace myself. Somedays, I just don't have it in me to train hard, so I take it easy. Other days, I have alot of energy and exceed my determined workout.
I guess in the short of it, listening to your body, feeling it communicate with you, it will guide you. I am not totally where I want to be yet with my training, but I will get there by spring for the triathlon. Still haven't decided which one yet, I'll post when I decide.
Keep focused on your goal, if you want it, it will be yours!!!
