its only sore when I move and bend my arm, I was biking for like an hour after it got stuck so I think thats why its in so deep. Im so used to pain it wont really make a difference when I try to sleep. Im just gonna wait a bit and see if it comes closer to the suface and if it looks like its getting any worse or if it discolors or whatever then i'll go to the hospital........anybody know what I should be looking for when I check for an infection?????just like dark colors and irritated skin or will it be harder to spot????
