Hello, you already have a C5-6 disc degeneration, a prolapse of the disc will cause radiating pain
in the arm with associated numbness
and weakness of the hand. Smoking will only aggravate your problem and 15-20 cigarettes will definitely reduce your pain threshold, will increase disc degeneration and also will cause anxiety and chest discomfort
. First thing you need to urgently quit smoking, drink lots of water/fluids and meet a neurologist
or a orthoapedician for examination and further management. Thank you, get well soon.
