You are not alone! I get cramping in my wrists, and even hands curl and lock so badly I have to stop.
I hope the rest is ok to post....
One thing that does help sometimes. I have found adding a bit of Icy Hot , Ben Gay or some sort of mentholated rub CREAM,
Add a dab on wrist from the tube and rub in using all over on wrists only, not your fingers to get marks on fabric.
Also word of warning as we age our skin gets thinner RUB GENTLY, so it doesn't get too hot. Also, caution I found Capasin (made with hot peppers) burns me.
