back pain
"It works.  I always take Bayer when I have a headache, and it always works.  I took store brand aspirin for four days battling a headache, and it just DID NOT work at ALL.  Popped two expired Bayer today and they still worked like magic on both my back pain from menstruation and the headache I haven't been able to get over.  I feel so much better that I literally went online to write a review about it.  If that doesn't convince you, I don't know what will.  Try it, it works."
