3. Tension headaches
Tension headaches are the most popular type of headache, and they are characterized by a persistent ache or pain around the brain, as well as a headache in the back or neck. They’re not as serious as migraines and aren’t normally caused with nausea and vomiting, but they don’t typically prevent people from going through their daily lives (so they’re just a pain).
Tension headaches are often treated by over-the-counter medications such as aspirin, ibuprofen, or acetaminophen (Tylenol), which doctors say are triggered by neck and scalp muscle contractions (including in reaction to stress) and likely changes in brain chemistry.
