Yes, Excedrin Back & Body will work. All of the Excedrins that I have tried have the exact same active ingredients...they just label them differently. Excedrin Tension Headache and Excedrin Migraine are exactly the same, and Pamprin is the same too.

Valium won't help the pain. It will just relax you. If it's a stress headache it might help, but other than that, it won't do much.
