Driving with putters (Ion, Anode, Ridge, Spike) hurts my middle finger joint. I have tried a power grip, modified power grip, fan grip, birdie grip etc. and the results are always the same - stabbing pain on my second joint. Is it possible that there is something wrong in my grip that is causing too much pressure and torque to my middle finger?! Even the tiniest pull against the finger hurts way too much. So usually it's not even possible to do an approach shots with a putter and that sucks.
Of course it is possible that I have played too much or I have had a bad drive or something because this problem started so suddenly. At the moment I have to tape my entire middle finger and avoid using it at all. And naturally that is messing my game. I'm really frustrated and I'm feeling that I have to give up and stop playing this wonderful game

Probably I just have to rest and hope that this problem disappears.
