I soak mine in Epsom salts for about 15 mins in warm water,x

arnica cream or spray is natural and brings relief. I hope you have a good day

Get a parrifin wax machine and soak hands and wrap with towels. I remember great aunt doing tbis years and years ago for her Rheumatoid Arthritis. It works

Any kind of warm helps mine ( sometimes just warm wet compress); and of course when it's a bad day, trying to be more still & not over using my hands. I have all kinds of things to help me open jars ~ Hope you feel better today !

I find exercising them helps though I think I have carpal tunnel. But in any case those exercises would help you. Maybe if you look up Carpal tunnel exercises you would see some exercises to do and they would help. Before you exercise them stick them in warm water as hot as you can stand but not boiling. Also putting them from hot to cold water back to hot or relatively warm enough that you can stand would help too. Then do the exercises with them.
