good day friend,
,You probably did not have a
fracture, my friend.You probably have a severe
bruise and
contusion and will not worsen your condition with any movement. It will heal with time and does not need an x-ray or antibiotics. Likely unless the red area spread he did not have an infection from the splinter either. I would not recommend you getting or borrowing anybody's medication or narcotics either, because this pain will improve with time and you do not want to get addicted to narcotic substances. cheers
