Grass pollen is hanging around at moderate levels too. Rain won't necessarily save you. A good rain can knock pollen levels down for a while, but thunderstorms can also break pollen particles apart and stir allergens into the air, which may make things worse for some people.

A writer at KFYO Lubbock News Talk suspects the pollen is feeding a headache with its own nickname, the "San Diego Chargers headache." The pain traces the lightning bolt on the old Chargers helmets, running from the right temple, over the side of the head and down behind the ear. Most of the time there is no constant pain. Then a sudden movement or a sneeze makes the whole right side of the head feel ready to explode.

If you have a headache, runny nose or congestion without other symptoms, don't automatically assume a cold, the flu or COVID. It could be seasonal allergies. Allergies aren't the only explanation, though, and those illnesses can share some of the same symptoms.

Not quite extreme is small comfort when one sneeze feels like a lightning bolt.
