I have spent ages trying to find out what it could be and found nothing. I would be greatfull if anyone has any ideas.
I followed the instructions, found a very tender spot near my armpit towards the back, massaged it.... and AM BETTER! Good luck!
Organ malfunction? Seeing a chiropractor for anything other than a massage is not only reckless, it will do nothing to cure organ malfunction of all things. These "professionals" are not allopathic medical doctors, they are merely doctors of chiropractic medicine, if you can even call it that.If you need a massage, see a chiropractor. If you need medical attention, you need to see a physician with a doctorate of medicine. The pain under your shoulder blade is quite common and known as rhomboid spasm. It can occur from overuse of the shoulder and sleeping on the left side can produce exacerbation of the discomfort by way of compression against the rhromboid muscle region.
good luck
Could be pleurisy...I've had it numerous times. I have an auto immune condition and this is common to have pleursity with it.
