Hello doctor I was using the wrong pillow two months ago. Since then, I started getting shoulder pain. Now the pain is there, only on left shoulder, neck region on left side and left upper arm. I am unable to move my hand or lift it high, I get pain in upper arm. Currently I am traveling and cannot access doctor for few days more, how to relieve pain? I have history of hypertension, degenerative disc in lumbar region and high uric acid in past. Thank you.
