I have tinnitus and the feeling that I have little marbles running through my head when I move quickly or am exposed to a sudden noise after stopping Cymbalta. Is this normal? How long will this last?

Sensations of small balls in the head, hypereactivity to stimuli. I was taking generic Cimbalta for 3 months, before Effexor for 1 1/2 years for anxiety. Changed for neuropathic pain.

1 week every 2 days, 1 dose every 3 days on 2 occasions and half a tablet. No medication replaces it... In fact, I have much less stress in my life. I was going through a difficult period at the time. Cimbalta was suggested to me for the pain. What I feel is at the level of the head, impression of small electric shocks more frequent at the end of the day and dizziness (as in a merry-go-round which falls quickly), I also have tinnitus and tingling
