Neck and upper back always tight and crackles and gets worse with any excersise

had this pain for about 6 years now It originates from between my right shoulderblade and spine. When i flex that muscle pulling my shoulderblade closer its always painful. Even excersise with very light weight does not improve pain. Its always there. Also the surrounding area around shoulderblade is always in pain. Under shoulderblade on top of iton the outside top shoulder, right side of my nwck is always tight. The whole area around shoulderblade feels painful. And also when i wipe my face with towel whatever long muscle that pulls the head back goes all the way to the mid back sometimes instantly gets cramps and locks my entire upper back and ribcage. Feels like a pinched nerve.

That muscle from neck also seems to pull on the shoulderblade muscle and triggers it too.

Pushups make thw muscle lock up and cause alot of pain next day where i cant do pushups anymore for about 4-5 days or more. I get massages every 2 weeks and chiropractor and no change
