I am dealing with RA or a close relative and use various natural approaches to free myself. Several months ago I had my stools analysed for bacterial composition; the findings indicated imbalances in the gut biome. I was also advised to heal a leaky gut.
Cutting a long story short I stopped eating grains, dairy, sugar and fruit to "starve" the bad bacteria. I eat lots of green vegetables and saturated fats; with small portions of eggs, fish or chicken, and I include some beef bone broth concentrate with every meal.
After all this the stiffness and pain continue and my last CRP reading was 81; much too high. I am not sure what is going on.
I try to maintain a positive mental outlook and have found inspiration in William Irvine's book, A Guide To The Good Life, The Ancient Art Of Stoic Joy. The Stoic's had some great ways to deal with adversity.
