1st thing is get your primary, rheumatoid, pain, PT etc all in contact with each other sharing notes. I’d also explore optional pain management modalities. Self-Hypnosis works well for me in limiting how my pain affects me. I tried the morphine’s, oxide, benzos, patches, creams, etc. Trial and error will become your best strategy. Keep a journal, diary, log etc of time pain is worse, what you were doing at that time, and what helps.
