Hey Wingman,

As you know, after you've played guitar for a long time, your fingers develop calluses. These calluses make it much easier for you to press down on the strings, because your fingers are not soft like before... As in, imagine pressing something with a brick, rather than a water balloon... :)

Anyway, if you develop blisters on your fingers, it means your calluses are rubbing off! It means, you really shouldn't play guitar until you've healed up! :O

Hope you can recover from this quickly, but I strongly suggest to not let yourself play until and unless your fingers are totally healed up... :/
