Haha, this might sound ridiclious but I'm too stoned to think right now. But. A stoner-related accident happened that resulted in my hand getting banged, it made quite the crack and theres a picture below. The less high I get the tripper the thought of having a broken finger is!
Ok well I don't know much about fingers but fingers are the most frequently injured part of the hand. They're constructed of ligaments which are strong supportive tissue connecting bone to bone, tendons which attach the tissue from muscle to bone, and three bones called phalanges. There are no muscles in the fingers so they move by the pull of forearm muscles on the tendons. By the looks of your picture it looks as if one of metacarpal bones may be broken. If you are feeling a sharp pain that may be the case. I suggest you get a doctor to check it out.
