I'm not qualified to diagnose or recommend treatment.
Something should shave the edge of it though in my unprofessional opinion.
I was prescribed Cymbalta years ago for nerve pain following amputation.
Being an anti anxiety /depression medication I got off it. Due to handgun laws and not wanting the stigma directed towards me and conflicting with gun laws...
I can say it shaved the highs and lows from emotion range. A midrange result so to speak. No , not drooling or unable to use my brain. Yet other pain meds affected my abilities...
P.T.S.D , I'll call it mild. Dogs bark. Loud noise ect. jangles my nerves. Not bad. But as if I'm hyped in senses.
If I lay on my left side at night my brain kind of races. With odd subjects. Not bad , but busy and distracting and no sense trying to interpret.
Right side? "Normal". Figure that out...
