It sounds like a migraine. I get frequent migraines and bayer usually works for me. Try lying down in a dark, quiet room, Put a cold compress or rag over your forehead, massage your scalp using a lot of pressure, put pressure on your temples. Avoid stressful situations and foods that may trigger migraines like cheese, and drinks like alcoholic beverages, and caffeine.
Try taking acetaminophen like tylenol or Excedrin Migraine. If none of this works. You may need to see a doctor. Maybe, you need to see a optometrist for a stronger presciption for your glasses because eye strain can trigger migraines. Or just try resting your eyes.
