Guitar and blood electrification

Hi everybody,
I have just started using my sota silver pulser fot blood cleansing, and i was just wondering if it was safe to use on my wrists in terms of whether or not the electrical pulses could cause my nerves to become less responsive in the long term which would be detrimental to me as a keen guitar player? Of course i am probably worrying about nothing but just want to be sure- any long-term zapper user/guitarists out there?

Cheers
