Sorry to hear you're suffering with throat pain. Of course it's always possible that it's related to allergy, a throat infection, or something totally unrelated to GERD. If it persists, please go to see your PCP. It's not something to ignore.
Drink plenty of liquids, keep your foods non-irritating and non acidic/spicy. If it were your esophagus I'd recommend Carafate suspension, which helped me through many a about of esophagitis before my Nissen.
I hope you feel better soon. Let us know what you find out!
