Dear Doctor My daughter has smashed finger between a gate and fractured the right thumb, also detected subungal hematoma which doctor mentioned is okay as long as there is no pain or discoloration. The finger is swollen just below the nail and has turned slightly yellow. But no pain. Would it heal by itself? Looks like pus, but it is not oozing. Any ointment that can help dry the wound? Or will warm compress help?
