I stabbed my palm about a week and a half ago, the knife went in at an angle in the middle of my palm, about 7/8th of an inch deep, maybe an inch, and about as wide. It s healed well sofar but with an bump/knot, and with a huge bruise still the size of my palm almost. And when it hurts it hurts all the way up to my arm till right below my elbow, a throbbing pain, doesn t do it much in the day if any unless I strain it, but it does at night. And i still can t extend my hand fully, about 80% or make a fist without it hurting, or put a lot of strain on it. Is this anything to be concerned about? Mostly worried about the bump.
