Hi, my son is 22 years old, living in Bethlehem, PA playing baseball and is having horrible allergy issues. He is allergic to most grasses and plant life. He is taking daily medications (flonase, an inhaler, and loretadine) but says that he nose will not stop running and he has had three bloody noses this past week already. Is there something else he can take? He has tried Benedryl but that has not helped.
