I have been taking Duloxetine for 10 weeks now for nerve pain. Having failed to tolerate Amitriptyline and Gaberpentin my GP is keen to keep me on this drug but says the alternative is Carbamazepine. I've read up and got a bit apprehensive about this and am thinking perhaps it is case of better the devil I know!

The only side effect that has consistently bothered me - even on the lower doses - is jaw clenching. I saw an oral surgeon who has made me a mouth guard for night times and I do use it. But I find that I'm clenching all the time and my jaw is always aching now too and I've been suffering from severe headaches too for over a month.

I don't know if this is the Duloxetine or simply a coinicidence - the jaw crunching definitely started at the same time as I started this drug. But it does seem to make a difference to the nerve pain so I really need to know whether it's worth increasing the dose or if the jaw crunching is going to persist.
