I also have a couple of gadgets that I use to stimulate my affected left side.
Exfoliating gloves, which I wear on my good hand and gently rub up and down on my left arm/hand.
A facial massage roller, which I use on the left side of my face and up and down my arm.
Both inexpensive pieces which I can do regularly and don’t need help with.
Hi Mark, touching lots of different things should help too. I was advised, due to altered sensation, to keep touching lots of different textures. Things like the arm of the soda, tables, brysh, comb, paper etc etc. It definitely helped.
