Hope this can help people work a lot with their hands.
As massage therapists, we use our hands a lot, I found a trick that:
When your hands start sore and tired, then you squeeze your feet or flex and extend your feet, most time you can feel cramps on your feet, wait until cramps go away, then your hands will feel relaxed.
And joint sore, you can try to stretch the middle thigh, then feel some release.
Or a couple of 30min walks every week.
I found some massage therapists will walk a lot before and after work.
This is from TCM, sometimes hand problems we will work on feet too. The middle thigh is the liver line, the liver controls the soft tissues in Chinese Medicine.
Hope this can help with your hand soreness. Until they get worse.
