Used it for years and LOVE it!
I have been using Pain-Aid since 2000 when I added Zee medical to our office as part of the completion.  Had a headache one day and whammo!  It killed it dead in 15 minutes.  My former wife used it successfully for years for actual cluster headaches (similar to migraines).  I am a dedicated user, although I wait until it is bad before actually using to avoid getting crazy with essentially aspirin and some additional stuff.  The sales/service guy who used to service our kit said it was really all in the &#34;less common ingredients.&#34;  I am betting it is the salicylamide (similar to but not quite the same as asprin and used to be used in so-called &#34;headache powders&#34; and caffeine which is an analgesic enhancer in small doses.  Whatever it is though, the stuff works.  BEWARE though, the extra strength version is a different formula, including no salicylamide and does NOT work as well.
