Tosillitis inflamation again? Could his have caused it?

I've had tonsillitis almost for a week and the swelling finally started to go down about 3 days ago and I decided to drink 2 cups of orange juice which is acidic because my tonsils weren't hurting at the time. Now my tonsils look as tho if they are starting to become inflammed again and they hurt like heck. Could this ORANGE juice have caused my tonsils to inflame?
