I am a 32 year old male, two months ago i saw my doctor about sever back pain, after his examination order an Mri on my lumbar which showed central stenosis. though my lower back pain has subsided due some physio therapy. However my back muscles (primarily in my upper back) are extremely swollen as well as my neck, which is causing pretty sever pain which is worsening. i find myself tensing my back and neck muscles involuntarily. Any insiight or advice would be appreciated. Ihave not had an mri or ct scan on my upper back and neck. Is this normal or could there be other issues that have not been diagnosed?
