I find that the best thing I can do is to keep the affected joints moving with moderate daily work. My physical therapist always said "motion is lotion".
BTW, I have digestive and other issues that make me worry about taking most NSAIDs. I started using topical Voltaren. My gastric doc told me I was kidding myself if I thought it was much better for me, even for gastric problems, than oral drugs just because it was topical. For liver, kidney, or other issues he said it had no advantage because the topical stuff got into the blood stream just the same. I am not so sure that it doesn't help by allowing the dose to be somewhat localized, but he wasn't buying it. In any case I decided to stop using it and mostly just live with the pain only taking an oral NSAID rarely when things are especially bad. My primary treatment plan has been to just keep my joints moving every day with a level of work that brings pain, but a level of pain that is manageable. So far for my hands that has been working for me at age 68. I know that my mom continued to knit every day with pain at 97. She said she needed to to keep the joints moving to manage the pain.
