I have a massive headache and i feel shaky took two tylenols (acetaminophen) but they didn't help?

Home remedies: You can try a few home remedies starting with ice application over back of neck and temples. Other things you could try are warm compresses, massaging your temples and green tea.

First Time or Worst : If this is the first time or the worst your headache has ever been, you need to seek immediate attention. If this is a chronic condition, then you need to find out prevention. You should have a doc help you with deciding whether more involved testing is indicated before starting meds.
