I came apon a distressing experience earlier tonight while practing. About half way into an arpeggio exercise I was working on my pinky finger on my fretting hand pretty much just went dead. There was no numbness of any sort, no pain either, just all of a sudden without notice I had almost zero strength nor dexterity in the finger, it just felt awkward. I use very low action on an electric so it isn't as if I really need to exert much strength at all with any of my fingers, it was really like it had no leverage over the strings. And I wasn't really doing any extraneous(<--spelling) fingerings, nothing I haven't worked on a thousand times before anyway. This scares the hell out of me. I've been playing bass for almost 15 years and I've never once experienced this. I've gotten a little numb before and had to work out the kinks for a bit but this just wasn't like that. No matter what I did I just couldn't get that finger back up to par with the rest. I stepped away a few times for a few minutes but each time I came back the finger literally went dead in seconds. I'm absolutely going to the doctor tomorrow to get it checked out, but until then this is gonna be eating away at me. And lucky me, I hit the coffe pretty hard earlier anticipating a productive night of practice, now I'm gonna be up all night worrying about this. Ughhh... So I was really just curious if any of you have had a similar experience to what I've described? And what the cause turned out to be? This is just really bothering me.
