Hi I Have Been Having Issues Where I Get A

Hi I have been having issues where I get a sharp pain in my upper back and chest when I tilt my head back. I went to the doctors and got anti inflammatory meds and muscle relaxers but they have not worked. Sometimes when I am lifting an object I get a pain in my chest and back areas and feel like I'm not as strong as I used to be before this pain. I mostly feel the sharpest pain when I am stationary. Especially in the morning.
