hi,
thank-you for providing the brief history of you.
Since you mentioned you have this symptoms of pain which nagging , and shoulder blade hurts alot.
First to ask? are you taking any self medication? if so please don't. Because what happens is when after taking the self medication the pain doesn't come down then the physician can also get misguided. Well this was the safety issue to talk.
Let's come to your pain, since your pain is in the upper back @ shoulder blades and post that the arm, burning sensation etc.
What I will recommend is to under an
MRI of
cervical spine to rule out any
soft tissue Injury. Once the scan rules out the soft tissue is not injured the next step can be taken to diagnosing.
Well, what I will recommend is first you use hot water fermentation over the upper back region below the neck. As
vasodilation will help the muscle spasm to come down.
Also try performing some simple neck exercises which will help the neck muscle to become stronger.
Also , perform Breathing exercises as well.
later stages you can proceed to upper limb strengthening exercise.
with the grace of God I wish you a speedy recovery
