I've been having recurring headaches since i was 12 yrs old (i'm 26yrsold now)3 times a month they usually subside with tylenol (acetaminophen) . but for the past yea?

Recurrent headache: Sorry to hear you are struggling with this problem. I encourage you to keep a very detailed headache diary to try to find triggers that you can then avoid: track sleep, foods, drinks, alcohol, activities like TV time, reading. Get your eyes checked and wear glasses if you need them. Stay hydrated with water. See a doctor/neurologist for treatment options: some meds can be used daily for prevention
