Hawthorns can create similar problems. Spikes just aren't quite as long. Cut one down a few years ago and ran one of the spikes into my ankle when moving the branches around. Hurt like Son of a B ****! Hadn't had a Tetanus in over ten years, so off to the ER and a couple of shots to handle the Tetanus and potential infection which is a real possibility. Hurt for days. Don't wait too long to go though. If infection has a chance to set it good, you are in for a round of I.V. antibiotics. NO FUN!
