Welcome!! I'm confused, the muscle tremors and stiffness has just started since starting the Cymbalta? I would get her to PCP and get her off the cymbalta, a lot of these anti-depressants can cause suicidal thoughts. I am a long time sufferer of depression and have tried a lot of meds. I am currently on Lexapro, which was working ok but my PCP put me on abilify as a booster and I haven't felt this good in years. I would definetly get her into counceling with a therapist, where she can maybe talk things out. I can definatly understand where she is coming from. Keep us posted.Good Luck and GOD Bless!!
