Hi there!! I've been thinking about you as well. I wish I had some good tips to offer you beyond what's already out there but I don't except to say perhaps you can be referred to a pain management person or try some alternative medicine remedies/treatments, although sadly those aren't always covered by insurance. Maybe some massage therapy, acupuncture, Reiki, or meditation can help to some degree while not introducing any more drugs into your body.
If I can think of anything else I will certainly pass it along. I'm wishing you all the best and thinking about you a lot
