most helpful answer a fractured bone unless it's sticking out of the skin can only be diagnosed with an x-ray. if you are unable to move your thumb if it's black and blue if you're in a lot of pain if the thumb is swollen then you might want to get it checked out by a doctor. of couse all of the above symptoms could occur even if your thumb isn't broken. a sprain also could cause swelling pain and bruising. if you think your thumb might be broken you don't want to mess around. delaying diagnosis could result in decreased blood flow to the digit which could cause a permanent inability to use the thumb. when in doubt check it out. i hope your team won the soccer game!
