Annie: I to have occasional spells like that and know it is no fun.
What works for me is filling a sauce pan half way with some Witch Hazel, dump in some ice cubes then soak a tea towel with the mixture. Wring it out gently and wrap around my hands for about 5 minutes at a time.
I am so sorry you, too have to suffer through times like these. I look forward to seeing you back in the next challenge. Big gentle hugs for you kind Annie.
