It first happened a couple weeks ago. I was practicing guitar at around 9:30 pm and when I finished and was getting in bed when I felt a sharp pain in the middle finger on my left hand. I know It lasted for at least an hour but I fell asleep so I'm not sure. It was gone when I woke up. I didn't get too worried about it since it went away. Just this morning around 10:00 I was in my mass media class on the computer and it happened again on the index finger of my left hand. It wasn't near as bad a before. The first time I couldn't touch anything without a really sharp pain running from the tip of my finger to the joint. It was kind of on and off all day. Any ideas what it is? Should I be worried? Can it be fixed?
