nessie,
LPR does cause sinus/allergy symptoms as you well know but I've never had the stinging, runny eyes. Or, nose for that matter. My nose gets so stuffy and I sniffle all the time but have drainage down my throat if at all. I have allergies in addition to LPR so don't know what's what some times? I don't usually have runny eyes or sneeze at all and can't tell if allergy meRAB do a thing for me so can't answer your question. My last test showed no allergies but sure I have some and ragweed is bad. I remeraber FlowerGirl seemed to have problems with her eyes doing that. Maybe she will answer you. Haven't seen her online any? Hope you get better soon.
