Maybe but for what?
Hurricaine spray (http://www.
Beutlich.Com/documents/hurricaine/hurricaine_spray_drug_facts.Pdf) is used for temporary relief. It is not safe if you're allergic to it or similar anesthetics. More importantly, one shouldn't use any pain killer for a long period of time w/o seeing his/her family doc to be sure one isn't masking something dangerous rather than getting to bottom of problem.
