If your symptoms have been ignored then the cause of your problems may have been misdiagnosed,. Some of the things you mentioned-feet, knees , etc sound like some of the things I have been suffering with. But I know the cause of my issues (never successfully diagnosed) is Lyme Disease. I contracted it in 1992 after pulling off a large engorged tick. You have been out in the woods "hiking, hunting, fishing" . If I were in your position I would be on the internet researching that possibility because very few dr.'s will test. Additionally, typical treatments are not very helpful in the long run. Antibiotics may alleviate your symptoms but do nothing to provide a complete cure.
