Funny thing, you mentioned about Flexeril. Prior to my neuropathy, I was taking this muscle relaxant for my neck. I was taking it on and off for maybe about almost a year. I just took it 1x a day. I dont know if it was contributory to my PN, but I just remember, I was on it prior to my pain.

Who knows....Mrs. D is right, effects of the medicines to each person is individualistic. My husband was taking Flexeril about the same time I was on it but he does not develop PN (thanks God), though he has some back problems now.
