Sounds like pinched nerve to me, but...in both hands? So maybe not...
Hi!
I am not sure why you enjoy the vibrations in your hand. This can be really troublesome and if they start in your whole body then life can be really tough. You should inform your doctor, maybe this is due to low testosterone and supplementation may help. There are many other causes such as diabetes, thyroid problems etc which should be investigated.
Since a confirmed diagnosis cannot be given on net please consult your doctor regarding this. Hope this helps. Take care!
