About 6 weeks ago I took a tumble which resulted in my fingers on my right hand being bent back at the knuckle. Ever since I have been unable to make a fist or even grip anything tightly with that hand. The pain is greatest when I try to make a fist and originates over the knuckle of my index finger on the outside (middle finger side). It's best described as a tightness. Has anyone any experience of something similar, I could do with an estimated recovery time, as you can imagine not being able to make a fist or grip anything puts a big downer on my training.
