sneezing, runny or stuffy nose,
post-
nasal drip, coughing, sinus headache,
and watery eyes
Depending on the trigger, my seasonal allergies include watery eyes or itchy eyes, and especially post nasal drip, which was a huge problem for me when my allergies started in 2006. I went through a long period of post nasal drip, but no acid reflux at all.
