While there are actually twelve different types of headaches, tension and stress headaches are generally the most common. With a tension headache, the pain is mostly felt near the forehead and/or back of the head, caused by contracting muscles creating a squeezing pressure on the brain. Stress headaches — more commonly known as migraines — are much more intense and are typically accompanied by high sensitivity to light, vomiting, nausea, and blurred vision. The pain itself is more of a pulsing, throbbing pain at the temple(s) and/or forehead.
