Hello Mario15: I just wanted to say that I have had this problem too & it is terrifying! I see that Glok has given you a link to some info on treatments. I hope this is helpful. Mine seems to have gone away at this point (hopefully!) I've been on Cymbalta for a couple of years now. I don't know if this has had anything to do with the fact that I don't seem to have had the problem recently. Best wishes.
