Okay, this is from my personal experiences and from what I am reading now:

Ibuprofen is great for arthritis. I took the limit of Ibuprofen for so many years that I am now allergic.

Exercise and movement - Try not to limp or favor a leg or foot, if possible. Stand straight, no crazy postures.

Simple stretches that are not overdone are great.

Sit up straight. We tend to slouch and use crazy positions while sitting.

Eat well. Calcium rich foods and well as other good foods such as veggies.

Use real butter and not margarine. Butter ahs 2 ingredients at most. Lost count of oleomargarine. Did you ever see that show about what's really in a Twinkie? It's scary.

Yes, stay hydrated. I'm weaning myself off sodas. No wonder I'm so crabby.

Wear good shoes. Clark and Grasshopper make good shoes that won't break your bank.

I've had what is TMJ for years. Since I was 15. The jaw bone dislocates. I hate going to the dentist because my bite is off center and I have a under-bite for a day or so. Try not to clench you teeth. (I have a hard time with this one.) BTW, sinus issues can affect the jaw bone, even the lower one, since the lymph glands are there.

From what I'm reading; Try to reduce the wheat and gluten impact on your diet. Supposedly these can lead to easy weight gain.

Hope you feel better.
