I think there are a few people who can help you (I am not a doctor) but all I can offer right now:
You could try Satanic healing?

I don't know if they will help but try different anti inflammatory or pain creams for arthritis?
I remember also, when I had a stress fracture in my toe bone (I did not know at the time), my cat would come over, sit on my feet and purr. This was very healing as well and I believe it may have been much worse without her. It might be good to get her a cat. They basically look after themselves. If you treat them right they will give you many benefits.
Anti inflammatory foods (from a website, not me):
fruits, vegetables, cold water fish, (salmon and tuna) tofu, walnuts, flax seeds, soybeans, grapes, celery, blueberries, garlic, olive oil, tea and some spices (ginger, rosemary, turmeric)
And ok... this last one is something that most people here would disagree with and I probably shouldn't be recommending, but whiskey has anti inflammatory properties and I had to use it in a pinch instead of painkillers (I couldn't drive to get anything) for a really bad neck sprain. My nan used to drink some before bed so she could sleep better in her old age. Anyway it is a last resort type of thing but y'all are grown and can make your own decisions. So there you go.
