Well Mark, since you ask, I'm impressed by his ability to operate on himself. But that small, superficial hematoma would never have been a threat to his limb or to his life. It would also not have been at risk for infection unless he opened it... oops. But having opened it, and having stuck his finger in it, infection wouldn't be a potential threat unless he stitched the dirty wound closed... oops again. If they'd called me to the ER about this hematoma, I'd have told him to go home and ice it and elevate the limb to keep the hematoma from growing. If he were on aspirin or anti-inflammatories, I'd have told him to stop taking them. If I ever went camping with this guy, I'd make him promise not to touch me except to carry me to a real doctor if I ever got hurt. My two cents.
