Muscles in back are really aching/stiff. Two aleve help some but I want to take two twice a day until I can get to doctor. No allergies to asprin or rash etc. Advil didn't seem to help very much. My wife's Dr told her she could take three ADVIL every four hours when she had her dental surgery and then last year when she had her knee surgery. So if you can take that much Advil for short term, can you do the same thing with the ALEVE?
