What a horrible story! Okay, let's start with why your scapula is in pain. When the pain is burning it means that a nerve is being impinged, and that usually means a bone is pressing on the nerve. Unless you have had an accident that has pushed bones out of alignment, the only way a bone moves is a muscle pulls on it. So, let's go with the assumption that one or more of your muscles are in spasm and are causing this problem.
Here's a list of muscles that refer to your scapula, or the area right next to the scapula:
1. scalenes (huge, this muscle causes burning pain right along the inside of the scapula)
3. teres minor and teres major
5. levator scapulae
As I re-read your list of various treatments and therapies you've gone through, I didn't notice massage. Nice, relaxing massage won't work, but focused trigger point therapy could successfully treat the spasms that are most likely causing the problem. I've been teaching people how to self-treat trigger points for 20 years, it's amazing the results people get when they find the source instead of treating the symptom.
You've been through so much, I agree that surgery isn't always the solution, and it causes scar tissue so it can be a part of the problem. Did you read the Home Page of this website? It may answer some questions if you read about repetitive strain injuries. I know we can work on the muscles, and the odds are good that it will help.
Do you have any of my books? If not, I suggest you get the ebook version of Treat Yourself to Pain-Free Living
. Then do all of the treatments shown for the neck, shoulder, upper back and chest. Also, go to http://www.aboutcts.com
and then to the section titled "Anatomy Lessons." You'll see a graphic of the scalenes and the descriptive text that talks about how the muscle impinges on a bundle of nerves called the brachial plexus. The brachial plexus is the bundle of nerves that ultimately innervate your scapula as well as most of the upper body and down your arms.
Let me know how you're doing, I'll keep working with you until we find the source of your problem, and then we'll talk about the scar tissue and if anything can be done about it.
Wishing you well,
