Hey. I play tennis and im not a guy who usually does a slice forehand, but i guess i did and now my finger part is kinda injured. Here lol could find this http://www.dh.aist.go.jp/research/centered/dhand-link2/boneandlink.gif Im injured at the MP part, on the index finger. I THINK its the bones but it may somehow not be. Sometimes it hurts and sometimes it doesnt. Like if i play tennis on the morning, it may hurt in the first right hand hit, than it gets used to it. This is here for maby 2-4 months now i think. Anyone know the problem,amount of damage, and what to do to fix it? And no im not gonna stop playing tennis for a while to stop it unless its REALLY CRITICAL thanks!
