ST. AUGUSTINE, Fla. -- Pollen comes from trees, flowers and grass. It can give cars a yellow coating and cause health issues for millions of people like Noni Heers.
"I started getting really stuffy and sneezing uncontrollably and like I was coughing like crazy, my throat got clogged. It was awful," said Heers.
As the pollen count continues to increase, Physician Assistant Amy Dugan with St. Augustine Ear, Nose and Throat says there are signs to look for to indicate your allergies may be developing into a serious infection.
"Usually if the symptoms don't improve or they're prolonged, if they start running a fever, increased sinus pressure, facial pressure, drainage starts turning yellow greenish, then they probably should be evaluated," says Dugan.
Dugan said over-the-counter medications will work for some people, but others will require prescription-strength drugs.
"If it looks like it's developed into an infection, of course antibiotics are good. There are prescription antihistamines we can go to. There are some nasal sprays that are antihistamines that we also use," said Dugan.
Since allergy symptoms can mimic a cold, doctors say if you have itchy eyes -- it may be a pollen allergy.
