In fact, some local hospitals say they're seeing a surge in the number of people complaining about itchy eyes, congestion and sneezing.

Doctor Arif Seyal is an allergist at Kaiser Permanente's Rancho Cordova facility.

His advice? 

"Go back on your allergy medications. Get your nasal sprays out. Most of the people with minor allergies will do okay. People with asthma, they should be ready with their controller medication. That is very, very crucial. This is just the beginning of the season. The worst is yet to come." 

Seyal says the allergy season doesn't really hit its stride until spring time. It starts in March when oak, olive and birch trees begin releasing pollen…and then gets worse in May when the wind starts kicking-up grass pollens into the air.
