Allergy season runs from around March through October. Tree pollen dominates in spring, grass in summer, and ragweed in late summer and early fall. In people with an allergy, pollen exposure can trigger the hallmark allergy symptoms: sneezing, watery eyes, stuffiness, scratchy throat, wheezing, and coughing. There are many ways to manage allergy symptoms, such as using over-the-counter medication, taking allergy shots or oral immunotherapy to help the immune system better tolerate allergens, and reducing one's exposure to pollen.

At any given time, up to 15 million people in the United States are believed to have brain aneurysms. Most of the time, brain aneurysms don't cause any problems. However, they do rupture in about 30,000 people each year. When an aneurysm leaks or bursts, it increases pressure in the skull, causing damage, swelling, fluid buildup, and sudden, severe head pain unlike any other headache. It's a life-threatening medical emergency and needs to be investigated at an emergency department immediately.

Tinnitus is widely believed to be caused by hearing loss. But that theory hasn't explained the cause of the problem for people with normal hearing tests who still have tinnitus. Increasing evidence suggests that some of these people have "hidden" hearing loss: damage to the auditory nerve—which carries sound signals from the ear to the brain—that isn't picked up by conventional tests. The evidence offers hope that if perhaps one day auditory nerve fibers can be regenerated, it might help reduce the perception of tinnitus.
