What is Vicodin's "main" purpose?

What is Vicodin's "main" purpose? i am prescribed it for a tooth i got pulled. it help the tooth. but i have a chief headache. advil and tylenol work better for headaches..
could it be vicodin giving me a headache? or is its pupose not a sedative?(like less acetominophine after advil maybe?)
im takin 750m vicodin.What is Vicodin's "main" purpose?
The 750 is Tylenol or acetaminophen the first number is the hydrocodone.It is a niggle reliever but as it wears sour sometimes it does cause a headache.If you can capture by with newly Tylenol or Advil it would be better.
It's purpose is to relieve pain. If you don't obligation it and something like Tylonol will work basically fine for you, then don't use the Vicodin. It's outstandingly addictive.
It's a pain assassin. If you still have a headache while on vicodin, you should consult your doctor. It may merely be a side effect, but even if it is - he should be able to prescribe you a different aching killer.
All except what it is touted for on Internet.
