I have had foot and ankle pain for about 15 years no Drs. Had any answers. I quit smoking and it improved some so I have stayed quit. Recently I decided to limit carbs to lose a little weight. My feet feel the best they have since I was in my 40s. I have experimented some and bread is the thing that makes my joints hurt. I love bread but I like not hurting better than bread.
And I have made a couple of trips around the west. My arthritis was much less on those trips than here at home. Don't know if it was the humidity or elevation.
