I had surgery with Meyers, April 07. At 6 weeks I sought neural therapy to help control pain, as I too felt no relief from the pain experienced pre-surgery. I was just thinking about this the other day, so I'm glad you asked. Neural therapy improved healing, for sure. Not only was my pain better, but the incision site also healed much quicker. My naturopath told me it's like cosmetic surgery for scars.
That said, I was still in pain for a while longer and even to this day, over a year later, I'm not 100% pain free. More like 85-90%. Neural therapy helped, though, and I would give it a try if I were you.
Now, I've also had platelet injections for a different issue (I think that's what you meant - they take blood, spin it in a centerfuge and take the platelets that were separated and inject them into the wound site). I am not sure how long you should wait before you consider this approach, though. For my knee, it helped, no doubt. I'm definitely an advocate.
10 weeks out, to me, is the crawling stage, using a baby analogy. This is not a lot of time to heal and the process could take months. Are you working out? Have you tried to "grit through it" like Meyers would suggest? Be patient...depending on how long you've had the injury you might be in for a long recovery period. Or, you might have some other issue (labrum tear or other tear) not addressed by Meyers.
He did find a tear and repaired it, correct?
