Burning my fingers to play better?

Question

i have a habit of hurting myself for a reason only i could understand...

i play a bass guitar and for the last 2 months ive used up about 5 lighters just burning my finger... my left index...

before i did it to harden the tip of my finger to play my bass guitar without it hurting... but now that my finger has a callus on it... can i keep doing it or is that unhealthy?

Answer 1

that's probably not the smartest thing to do

Answer 2

It's unhealthy if you burn inner layers of your skin & nerves.

If you keep playing your guitar, the callous should remain because it will keep getting rubbed by guitar strings.
