John,
Thanks for your reply. I don't know Dr. Forbes, but I suspect the surgeons all know one another. As for the saddle stuff. Unless you didn't have surgery through your sternum, I don't think I'd recommend too much horseback riding, except for some very passive kinds on a gentle horse. Treat your sternum like any other broken bone. If you abuse it, it will come back to bite you--hard! No roping or other stuff that roughly yanks on your chest, especially outward. I'd say 8 weeks is way too short a time post surgery for stuff like that. Perhaps 3 months or more would be more realistic. Doing it too early is a way to cause dehissence (sp?) which means the halves of your sternum come apart again, possibly never healing right again short of bone surgery. Pain is your best friend--listen to your friend's advice. If it hurts--especially this early on in healing--back off!
As for me, my sternum healed solidly. I drove at 4 1/2 weeks due to my farm location, did not lift above 10 lbs. until six weeks, about 50 lbs. by ten weeks, and both kids (then 40 lbs. and 70 lbs.) at about 13 weeks. Chicken feed sacks, heavy rocks, etc. were pretty much back to normal by about 3 months. I have not regretted taking my time getting back into physical activity. There was a time I babied myself, and there was a time I pushed myself. When there was pain--I backed off a bit for a while, then when the pain went away, I pushed further. Now I can do more stuff than before surgery, but it's also been nearly a year since the OHS, and my scar is pretty big still--some keloid development due to allergy to the 'dissolving' suture used on me. When I do climbing or other activities that involve extreme stretches for the first time since surgery, I feel peculiar pulls and 'twangs' in my body, but after that time or sometimes the second time, it's smooth sailing.
Face it, so far as your body is concerned, you've been stabbed in the heart with a sternum-splitting battle-axe. It doesn't know that you paid over $100G to the surgeon who knew where to split and stab, just that it happened. It takes time to recover from such trauma--take it easy. You'll be in all our prayers. Feel free to come and post stuff if you feel depressed at some point, or concerned about what we call a "bump-in-the-road." Or just come on by to say hello.
