Still neck, shoulder n back pain after 1 year n 26 physio session. What other treatment options except total disc replacement surgery?

Large breasts. If you have large breasts this may be contributing to your neck, back and shoulder pains. Seek consultation with a board certified plastic surgeon.
Many. I recommend you see a good pain doctor. There are lots of options including medications, chiropractic, acupuncture and minimally invasive injections. Check out paindoctor.Com for a good doc near you.
