pain relief?

My bf had back surgery 6 years ago and recently his back has been hurting again. He went to the dr and they said he has spurs on his 3 lower vertebrae and the last 2 vertebrae are trying to fuse together as well as he’s holding weight on one side more than the other. The chiropractor recommended seeing him 3x a week for a month then getting another MRI to see about it and no strenuous activity but is there anything I can do to help bring him some kind of relief? He has to sit for work so he has a cushion for that and I have bought a few creams to try as well as the obvious which is take Tylenol and ibuprofen but nothing has helped thur far. Any ideas?
