A little over 2 weeks ago, I had cut my left index finger at the base while preparing dinner with an over ripe avocado - the knife slipped way faster through the avocado than I expected. So I got stitches and then had them taken out with no complication. However, now that I have "full" mobility of my left hand again, I find that I can't really make a good fist or grip. I tried pull-ups again and I can't grasp the bar as tightly as I would like to. My finger doesn't hurt anymore, but there is a deep scar that kind of indents into my hand. I think it might be keeping me from making a full fist. Should I just give it more time, or see a doc?
