yes acidic foods certainly can cause a painful raw feeling to the soft palate. this is especially true if you ate something crunchy earlier in the day causing microscopic tears in the skin of the soft palate. the fact you ate the fruit before you went to bed may have made a difference if you normally have trouble with acid reflux. during sleep stomach acid definitely can come all the way up the esophagus to the soft palate area. hope this clears things up for you!
i ate alot of acidic fruit last night then fell asleep can that be the reason my soft palate is sore and raw?
