It could be the weather.
We’ve had some particularly bad weather the last few days. I’ve started paying attention and it could be that my hands get tingly when there is a pressure change. So maybe bad and good pain days are not entirely arbitrary.
My sample size is too small right now, but I’m going to pay attention. Sadly, this appears to be a rare side effect in my online cancer community, so I don’t have anyone else to confirm with.
The tingly pain is only one of 3 side effects in my hands. The other two–hypersensitivity and dryness that leads to skin coming off–seem to have no relationship to the weather other not wanting a lot of direct sunlight on my hands for a long time.
