Allergist Castle Hills
Juniper Allergy specialists & doctors provide personalized care to adults and children with allergies, asthma, and immune system conditions.
Providing Expert Allergy Care in Castle Hills
Castle Hills is a small city about 7 miles north of downtown San Antonio, fully surrounded by San Antonio. Loop 410 runs right through it, and NW Military Highway is its main north-south road. Most of its homes date back to its early growth in the late 1940s and after, many with mature trees and big yards.
Juniper Allergy treats Castle Hills adults and children for hay fever, asthma, food allergies and skin reactions. Our clinic is at 255 East Sonterra Blvd, Suite 209, near Loop 1604 and US-281, a straight drive north from Loop 410.
Common Allergy Triggers in Castle Hills
Tree pollen is a big one here. oak pollen coats cars and driveways each spring, and mountain cedar pollen blows in from the Hill Country in winter. Pollen can travel for miles on cold fronts, so you do not need cedar trees in your own yard to feel it. Late summer and fall bring ragweed.
Asthma and Allergy Care for Castle Hills
Pollen and allergies are a common asthma trigger. If you wheeze, cough at night or feel tight in the chest when pollen is high, our asthma doctor can help. We check how your lungs work with asthma testing and find the allergens behind your flare-ups.
Treatment may include inhalers, other medicines and allergy shots to calm the allergies that set off your asthma.
