What could this pain in my head be? is tylenol (acetaminophen) just as good as excedrin?

More Info Needed: You should provide description of pain, location, duration, etc. To be able to answer. This may indicate a serious medical issue and should be evaluated by a physician. Both tylenol (acetaminophen) and Excedrin are mild-mod pain relievers, but Aspirin products do have effects on coagulation. You need to get a medical consult to determine type and cause of pain in your head.
