What can help with constant pain in back, hips and legs?

I have scoliosis, osteoporosis, osteoarthritis, a bulging disc and degenerative disc disease. I have had the steroid injections several times. Tried chiropractic over the years. Now they are telling me that surgery is my only option. Rods, clips, pins, etc. This isn't an option for me for a few reasons.
The bottom line is that I am in constant pain. I took gabapentin for quite a while and it helped. I didn't like the side effects and the way it made me feel so I quit taking it.
I am 68 and live alone. My closest family is 500 miles away. Any thoughts or suggestions will be much appreciated.
