I have what appears to be slight swelling in the left parotid and throat area with occassional pain during swallowing. The pain is like a needle stabbing me then it s gone. The first couple of times it happened it caused a spasm across the throat and it s only happened once on the right side. I have hasimotos disease. Had ablation 7 years ago. Endocrinologist suggested ENT for scope. What could this be? Just want to be informed for doctor appts. so I can give them the best information possible to diagnosis this quickly. I do have what seems to be excessive (at least to me ) ear fluid and in morning a lot of sinus congestion followed by drainage. but this swelling and pain during swallowing has been there for 4 months now. Thank you
