I don't know anything with certainty, even whether the sun will come up tomorrow. All I can do is conjecture, guess, theorize.
To me, given your injuries, it seems clear that you would have been crazy not to have Dr. Meyers fix you. But me? My injuries are probably not as severe as yours.
I've seen my body heal itself naturally of three injuries:
1. plantar fasciitis (a repetitive stress injury)
2. tennis elbow (a repetitive stress injury)
3. injured shoulder
For the plantar fasciitis, it took about a month for the symptoms to go away once I bought a bike and stopped walking so much every day to work.
For tennis elbow, it took, I think, about 2 or 3 months of avoiding any kind of construction or labor work using my arm for the pain to go away.
For the injured shoulder, it took about 6 months of avoiding basketball, and avoiding any weights, and being careful about sleeping on the shoulder, for it to finally heal.
So in each of these cases, it took a long time (months) for the body to repair itself.
Albert, what if you, as an experiment, took a cigarette and burned a simple spot on your arm, only as deep as the second layer of skin? In other words, not a cut but a burn. How long would it take for the wound to completely heal, to where the redness was gone? I'm guessing over a month. (Don't do it!)
Now consider that torn tendons (on your abdominis rectus) take much, much longer to heal than torn muscle or burned skin. The tendon/facia tissue is a miracle of nature, but I think it's reputed to need more time to heal. By time I mean *time off from hard usage*.
Keep in mind I have no medical qualifications. I'm surmising here. And I'm always looking for other perspectives that can change my mind. All I really care about is getting better. I'm looking every single day for thoughts of others that appeal to my reason, and can change my current, limited, certainly incomplete and erroneous understanding of this cursed disease.
Again, for your severity of injury, you'd be crazy not to get surgery. But now that you've had it, it seems reasonable to me that you consider that much of the literature on sports hernia says it's a repetitive stress injury (like plantar fasciitis or tennis elbow), and so there should be an element of *time off from hard usage* in your post-surgical plan. And I can't see how a major tear to the conjoined tendon of the abdominis rectus should heal any faster than an irritated tennis elbow tendon, or a frayed plantar fasciitis tendon.
