I am a 47 years old male. Due to a back injury in January of 2014, I was diagnosed with a herniated disc that resulted in a left leg numbness and lower back pain. My MRI sowed a multilevel degenerative changes of the lumbar spine, most severe at L4-5 where a 2 mm AP annular bulge with mild right and moderate left facet disease contribute moderate right and severe left neural foraminal narrowing. No canal stenosis at any level in the lumber spine. Since the pain was bearable, I choose to live with it and not to operate. Lately I am feeling pain and numbness in my left hand as well, and almost continuous headaches. I also feel aches and pains in my entire body , always feeling tired. Are they all related , and if so what should I do?? Thank you in advance Samer W. Kaibni
