ear ring got pulled. ?!

I am not sure what a "look" is so I am assuming you mean a hoop earing. Make sure that the back of the earring did not get pulled inside your ear and lodged there. If the beading has stopped you are probably fine. You should take the large earing out and wear small studs, preferably gold or sterling silver so they are hypoallergenic.

First make sure there is no part of the earring in your ear. Remove the earring, clean the area good with soap and water. Apply Hydrogen Peroxide to the area with a cotton ball-Alcohol is OK too. You don't say how long ago this happened but the throbbing could be from the trauma to the earlobe or if it happened a while ago an infection. If there is no infection, the Peroxide or Alcohol will help prevent it you must keep the area clean. I would not put any earring back in that ear until the trauma or infection is gone. You will now this by the lack of throbbing and not so tender to the touch. If you must wear hoops be careful this is a common thing to happen. I treated this injury frequently when my ladies were off duty. They were not allowed to wear hoop earrings while on duty.
I hope this helps you.
