Infected Finger Nail

One of my fingernails seems to have gotten infected. I am pretty sure it was from biting my nails. I have to stop that... Anyway, yesterday my right middle finger was a little sore beside the nail. That happens all the time when I bite them. However, this morning when I got up the whole left side of the last joint was red and it just got worse all day. Tonight I called and left a message with Dr. Awadh's nurse about it. I am hoping it is better in the morning. I have this horrible feeling that I'm going to end up having to have it lanced or something. Yikes.
