I have a problem

[heater]

My thumb has developed an indention and i can't fully depress my button on the twist.
Now i'm left thumbing it for awhile and using my gnarly thumb nail on the right. lol

I need to form a callous so i can stop being a tender thumb newb.
At least my eyes don't twitch or my tongue hasn't swollen so i guess this is just a minor inconvenience.

Anything that would form a callus would have to damage the tissue so scar type tissue would form. May wont to consider i piece of medical tape or a band-aid with the absorbent side over that spot on your thumb.
