As the title would suggest, I'm looking for any suggestions to help heal up a calloused finger as a result of finger sticks. When it started to build up (actually 2 fingers) I quit using those two fingers for testing. That was close to a year ago, and they still haven't healed up. The index finger is just a few tolerable hard spots, but the middle finger is still the entire fingertip. It is pretty thick and has cracked a bit in the middle with some very tender skin underneath. Sorry if that was a bit too graphic, I hope it wasn't. Anyway, again, just looking for what I might be able to do to help this disappear.
