• People who have spring allergies might start feeling their symptoms kicking in as trees have begun to pollinate.
• Symptoms can include sneezing, itchy eyes, coughing, congestion and fatigue.
• People who need to undergo allergy testing or treatment have several options.

Dr. Monty Trimble of Dallas Breathe Free Sinus & Allergy Centers said allergy sufferers have multiple treatment options available, depending on what is most comfortable and convenient for them.

"Sublingual immunotherapy or, as I say, allergy drops under the tongue, has been around for decades," Trimble told Lone Star Standard. "I think it's definitely become more common because it can easily be done at home and it has a better safety profile. I think the majority of patients, 90% or higher, will do just as well with sublingual as shots. While shots are still available for those who want them -- there's certainly patients out there who do better with coming in for a shot than trying to remember to do a drop a couple of times a day -- I do think that for many people, allergy drops are certainly much more convenient."

People who suffer from spring allergies might feel their symptoms starting to bother them in February or March, when trees begin to pollinate, according to Blanchard Valley Health. As wind spreads pollen through the air, it can come into contact with skin, eyes, noses and mouth to set off allergy symptoms.

Allergy sufferers might be allergic to the pollen of specific trees, such as birch, sycamore, oak or walnut. Different types of pollen have different features, which makes it tricky to develop a single allergy treatment to address them. Fortunately, allergists can test for allergies to various types of pollen and develop treatment plans accordingly.

The 50 million Americans who suffer from seasonal allergies might experience sneezing, coughing, congestion, itchy eyes, a runny nose and fatigue, according to Yale Medicine.

Testing for allergies normally involves a skin-prick test, during which a doctor will insert a tiny amount of potential allergens under the skin of the patient's upper arm. The skin will become red and swollen if the patient has an allergy, and patients typically have their results within one to two days. The other option is a blood test, during which the patient's blood is drawn and tested for allergens in a lab. Although this  method takes longer to produce results, it allows doctors to test for more allergens than during a skin test.

To keep your allergies in check, Mayo Clinic suggests staying indoors on dry, windy days when pollen is more likely to spread. Allergy sufferers should also shower after coming indoors to remove pollen from their skin. Check the pollen count on the local news so you can plan for when it is best to stay indoors and keep windows shut. Allergy sufferers can also try an over-the-counter remedy, such as oral decongestants, antihistamines or nasal sprays. If those solutions don't work, alternative treatments such as allergy shots or immunotherapy can provide relief.
