I would talk to your doctor about trying a course of pred and see how it affects you. Everything CFBoy says is true, but it takes doing them long term to suffer negative effects. If they work, even if it's only short term, it's really nice to have a break from constant pain. I finished my second course yesterday, they've been a godsend for me.
Either way, I hope you find something that works for you. Chronic pain absolutely leaves anyone depressed. 🤕
I asked a friend about CBD, he says if you do it, buy it from a marijuana store not a drug store. He says you'll get a better product at better prices. He says if you go to a good store, somebody there will be able to recommend the right one for your circumstances.
