Have you considered your diet might be contributing to your pain? I was dx'd with Arthritis in 1999, I took chemo with a maintenance dose of 5mg prednisone, until I discovered the Whole30 autoimmune protocol diet. I discovered grains and sugar were pain triggers. I now follow the diet closely and I do not take any drugs for my arthritis.
There is a companion book "It Starts With Food" that is an eye opener when linking modern foods with health issues.
It was written by Dallas and Melissa Hartwig. They have a website.
