My grandmother had a very simple remedy for this that worked so fast.
She would steep a bag of black tea in boiling water.(purified filtered water ) Don't use tap water because it has chlorine in it. Once the tea cooled she would drop tea drops into the affect eye and then have you hold the slightly warm teabag on your eye. Immediate relief! It seems the tannins in the tea is very healing to the inflamed eyes. Pink eye is very contagious so wash your hands.
Of course you can go to your Doctor for treatment but while you are on the waiting list , try this.
