When I was in cancer treatment, I started using pot for the pain.
I grow medical pot, make a coconut oil extract, and put that in pills. I finished a batch yesterday.
The stuff I make is roughly 90% CBD and 10% THC. That is good for falling asleep, or pain that isn't severe. The more pain you have, the more THC you need. When I was hanging out in a medical pot forum, the guys in serious pain grew strong kush strains. I'd suggest adding extra CBD in that case, but that depends on what works for you.
I am opposed to smoking, but vaping doesn't do much damage. The news you see about vaping is usually about manufactured tobacco products. I'm talking about vaping actual pot or hash (or concentrates).
Prices are crazy, you'll save thousands growing your own.
