Sneezing and shortness of breath

I've never posted here because until a couple of weeks ago my allergies weren't bothering me. Since the pollen has come into full bloom i've been experincing the common sypmtoms, itchy watery eyes, runny nose, sneezing, but when i sneeze i find it very hard to catch my breath for at least a minute, i have to take very deep breaths back to back. Has anyone else experienced this?
