Since doing my first century at the weekend I've got some issues with my left hand. Basically my little finger, and to a lesser extent my ring finger, is really hard to straighten. I also have a really weak and hard to control grip using that hand. There's no pain as such but I get a weird aching feeling further down my wrist when I try to straighten it. The fingers will go into their correct positions if you put them there but I can't properly control them. I'm pretty sure it was caused by my bike fit. My new stem had yet to arrive when I did the ride and as it was I was leaning a fair bit on my hands. I also kept finding myself gripping really tightly without meaning to. It's got a bit better but it's still really not right. Anyone had any similar experiences? I'm just wondering if I need to see a doctor or if it's something that will sort itself out in time?
