Tough one. Sorry to hear.
I was a competitive hoops player in college, but had to give it up following a serious injury. So, I can imagine how you feel being forced out of your sport because of a medical condition.
But – osteoartritis is very different from an actual injury. I think generally what you’ve heard so far may be the best advice: Continue to talk to & work with qualified doctors.
With that in mind I’ll just offer the following, for whatever it’s worth -
• From what I can tell osteo doesn’t heal on it’s own, even in younger people. It’s a degenerative disease that slowly becomes worse.
• Avoid trying to “push through” the pain to continue your regular running/training routine. Continued joint impact will not only hurt like hell, it’s possible it could even accellerate breakdown in your joints.
• Be careful with both over the counter & prescription pain meds. Most doctors will use caution in what they tell you to take, but many will fall back on pain killers just to provide you with relief as your condition gets worse.
• You haven’t said so, but I’m guessing you’re already seeing at least one specialist. If not I’d suggest you consult with a good provider with experience treating artritis and other bone/joint disorders. Your problem is already at a point where most sports med docs just won’t have much to offer.
• Finally, start learning as much as you can about long term treatment options. I’m only familiar with 3 – joint replacement surgery, stem cell therapy, and TENS (transcutaneous electrical nerve stimulation) pain management. Each of these has some limitations, and it’s likely none of them will fully restore your athletic performance. But with support from the right specialist you may find something that will help avoid chronic disabling pain.
Good luck.
