[|Human|] I  am 70 and in excellent physical condition...I have had severe to moderate achy pain in my left upper back that wraps around to my left front.  Years ago I had a gastric ulcer and the pain seems similar in some respects as it wraps around to my stomach area.  I want to press hard against my upper back area for relief or lie on heat....any thoughts?
[|AI|]  Hi, Welcome to Chat Doctor forum.  The causes for such pain may be the lung infection, muscular pain, arthritis of the shoulder, or gastric hyper acidity, Lately cardiac involvement.  I advise you to consult a physician for diagnosis and treatment. You may need to have an ECG, ultrasound, and X-ray, of the shoulder for diagnosis.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to hasten the recovery.  Wishing for a quick and complete recovery. Thank you.
