I am on Cymbalta now going on almost 4 years I started taking it for neurothopy in my arms. with out Cymbalta my arms are numb and dead wt can't move them hardly at all. I take 120mg twice a day. As for my side effects, my depression has worsen, the joint aches are severe, fatigue, constipation, diarrhea, vision problems, ringing in my ears, static and what I call electric strikes going through my head, and I have had suicidal thoughts and now I am having memory problems. I work full time and it is really starting to affect my job. I don't miss work but I am so tired and hurt so bad and I forget what I am doing, I wonder is it worth it so I can still have the use of my arms. just recently my doctor started me on Delfin 7.5 to help with my depression. I haven't noticed any difference yet. I am so tired of being in pain and the static and ringing in my ears and just being but I keep going on got to keep going on thanks for letting me write this
