It's that feeling, similar to a cold, but just doesn't go away.
Symptoms Alejandra knows all too well.
"I know I have allergies immediately, and then I have a headache. And after a headache I can't sleep,” Alejandra Rowell, who suffers from seasonal allergies, said.
Allergy season has officially started in Texas.
"Cedar season is generally the first pollen that we see. That starts first week of January, usually runs through about the second week of February,” Dr. Keith Paull, an allergist, said.
But allergies plague Texans all year-round.
''In Texas we have very high dust mite counts and high mold counts year-round,” Dr. Paull said.
Experts say the best prevention is to avoid wooded areas like this one at your local trails and parks.
So when should you just treat yourself, and when should you see a doctor for your allergies.
"Folks who don't get adequate control with their over the counter medications, you know if you you've been treating with antihistamines for two months and they're wearing off then you should see your doctor,” Dr. Paull said.
It's also flu season and Dr. Paull said symptoms can be very similar.
However, Alejandra said she is more worried about allergies this time of year.
"Yea, it is unavoidable because I don't think it depends on us, but the environment,” Rowell said.
But there is good news for those that are particularly sensitive to cedar; cedar season only lasts about a month.
Dr. Paull said allergists can do nasal irrigations that wash out allergens from your sinuses, and can also give shots that will help eliminate allergy symptoms.
