MrsC has Psoriatic arthritis.
She uses the arm-hand wrist warmer things. No fingers, just a hole for thumb. Extend at least halfway up forearm.
Keep blood flowing through wrist warm, helps with circulation to rest of fingers.
I was given a pair of these, from M&S, by D's Dad for Christmas. Shame the thumbhole was small and they looked to 'girlie' for D to use.
I had some plain navy polypropylene warmers but I don't know where I've put them.
D has some long-fingered 'tipless' neoprene gloves we bought from Coopers of Stortford a few years ago. They are coming apart at the seams but would be nice for sore, active hands. They've probably been discontinued but were chap...
