hey up.
this will work for your fingers and you wont need to ingest anything.
buy a chunk of root ginger (about the size of a fist) then grate it up and put it in a muslin square or a sock. bring a pan of water to the boil then chuck your sock in the water. simmer it for ten mins dont rolling boil it though just a simmer.its ready.
take a cloth, tea towel or whatever dip it in the water then wrap your hands in it.(hot as you can tolerate) as you get used to it you might want to put it back on the stove.
you could just put your hands in the pan when its cooled down a bit but i reckon you would find it a bit much on your skin.
let me kow how you get on.
oh …you might want to give the sock a squeeze with a spoon or something about five mins into the cooking.
makes the house stink mind.
i have used this on folks on chemo before.
