My advice is to stop eating foods that have more than trace amounts of
unsaturated fatty acids.  You are most likely overloaded with
arachidonic acid, which leads to these kinds of "autoimmune" problems.
You also may not be producing enough stomach acid.  You can try
supplementing with vinegar, and if you get "heartburn" type sensations,
that means you have taken a bit too much and you then know what your
needs are, if any.  If you do these two things (along with not cooking
food that contains cholesterol while exposing it to air - meaning boil
if you must cook) then you are likely looking at 1.5 to 2 years to see
a total eradication of the problem.  But you can't "cheat" by eating
the wrong foods "once in a while."  Even most breads today are made
with highly unsaturated oils, though French baguettes usually are not.
I make my own bread to avoid this problem.  Butter is okay, as is
coconut oil, dark chocolate, whole milk dairy products, and a boiled
egg a day.  If you like "meat," consider using gelatin and eating
boiled shellfish (if you can find any that isn't too polluted).  In the
meantime, eat antioxidant-rich fruit as well.  For beverages, lighly
roasted organic coffee and organic white tea are good, as is
seltzer/club soda.
