Hello, I am experiencing upper back pain located in between my shoulder blades along my spin. Its constant and gets worse when sitting which applies pressure to the location. It has persisted for over four months. My eye's also feel slightly bruised. I haven't lost my appetite and my stool and urine are normal. I do feel a bite light headed at times fatigued. I have no abdomen pain or discomfort. I am per diabetic. I control my blood sugar with 1000 mg of Metformin and 5 mg of Tradjenta. Please help.
