Hello Kay and welcome to CP and I am very sorry for all that you are going through.
I am not sure what it is that you do as far as work but I know for myself i sit alot at work when I manage to get in. One of the things that I have found that works for me is ice packs. God i swear they work better than my pain meds at times. I have even bought myself one of those little coolers and have been taking them to work with me. I trade one for another and sit at work with an ice pack down the back of my pants lol. I know it sound odd but sometimes it the only way I can get through my day of work. I have lower back pain from a car accident that triggered osteoarthris that I didnt even know I had before the accident and some degenerative disk stuff going on as well.
I know it doesn seem like much but I do swear by my icepacks I even sleep with the things. Will prob damage my nerves with frost bite before I get any (if any) relief from the docs and injections.
I was also wondering if they have concidered steriod injections? If not it may be an option to discuss with your doctor... I have heard that they work for alot of people even if its just temp. Im sure you are like the rest of us any relief is better than nothing at all.
I do help this helps you out at least a little sorry I dont have any more to offer up
