Happy you found a solution.
With eating only meat, how is your regularity? I emphasize veggies, nuts and fruit with my no/very low starch and I have issues if I do not emphasize the them.
Also I have incorporated sauerkraut and kefir for many years that really helped regularity as well.
How are other medical tests (blood pressure, cholesterol etc..). Everything is good?
Best wishes on staying pain free.
AS may win some battles, but I will win the war.
