I stepped on a iPhone charger and it went into my foot?

I stepped on the part that goes into the outlet and now it stopped bleeding but it's sore and hurts to walk on. Is there anything to stop the pain? Fast maybe?

Wash it with soap and warm water and put peroxide or an antibiotic on it. Put a bandage on. If its cut and very sore, keep your foot up higher than your heart, which will keep blood from rushing to it making it throb more.

Ice.

My daughter also stepped down and onto her phone charger & it penertrated the foot 1/2 inch. Today.
