To handle pain, I use Voltaren (which helps area like joint pain close to your skin (per package instructions). I also try to use my other hand to handle stuff like opening cans of food. I also go to the gym at least 4 times per week doing yoga or classes for senior (Silversneakers, etc.); on go on treadmills or bike, whatever makes me feel good, and not hurting. I used to walk 2-3 times per week outside with friends too (take fresh air & get vitamin D on sunny days) with sunscreen particularly on my face protected by cream with SPF30 or above.
