Oh no!!! Hope you feel better soon. That just makes me cringe reading that. My boyfriend got the tip of his finger pinched off on a machine at work and had to go through skin graphing surgery...they started with sewing his finger to the middle of his palm to give him skin on the tip of his finger then after that they took skin from the side of his leg to put on his palm(lol he grew hair on his palm...pretty funny and gross). So I hope yours wasn't as bad as that.
It's gotta be painful though. Take care and don't over do it. :)
