My hand physio recommended Thermoskin gloves for my inflamed fingers. Here is the importers website:
You can also buy them in some Lloyds Chemist branches, around £20 but worth every penny.
They are amazing and reduced the inflammation in my fingers within days. The breathable thermal lining keeps the skin warm so the micro-capillaries open up to let blood flow and the gentle stretch outer skin "squeezes" the inflammation from the fingers.
I say "reduced the inflammation" because its quite hard to eliminate the inflammation from fingers. But the improvement is amazing, I could type with them and the latest versions have a rubbery grip so you can wear them driving.
I wish I knew about them as soon as I was diagnosed...I'm still struggling to form a fist but slowly stretching the joints with physio help.
