Dodgers' Justin Turner -- Hospitalized For Mega-Pimple

L.A. Dodgers 3rd baseman Justin Turner shoulda oxy-cuted the massive pimple on his leg -- because it got infected ... and things got so bad, he was taken to the EMERGENCY ROOM!!!

It's pretty gross ... Dodgers manager Don Mattingly said Turner noticed something was wrong on his inner thigh on Sunday -- and was given medicine, but it didn't heal.

In fact, things got even worse -- so, he was taken to an emergency room where he was treated for an infection ... stemming from the pimple ... and missed the Dodgers game on Tuesday night.

Justin later said the pimple was an ingrown hair that "blew up" and got infected.
