Just like they said, you’ll build a callus soon enough but in the mean time, if it hurts real bad and you think it will bleed the next time you throw, but you still wanna yoyo. Then You can go to your local Drug Store/Pharmacy and go to the band-aid aisle, There you wanna look for some CoFlex for 3-5 Dollars and it works great, it sticks to itself and not your finger(kinda like an Ace Bandage without the clips that hold it together). Wrap a little strip about scotch tape size around your finger and your good to go. It will protect your finger and also help prevent the string from sliding around you finger when throwing, if you have that problem. The Drugstore/Pharmacy is the quickest way to get it, But I believe that you can get it here in different Colors, the Drug Store/Pharmacy has White or Nude (Tan) and it’s usually bigger Rolls too. But you can Click Here to Purchase it Here on YYE.
I like it when My Finger gets sore or when I have a cut on that finger. For those of you who don’t know or haven’t seen it here is a pic:
