I have been taking Cymbalta for a year for fibermyalgia. 2 months ago my dr. gave me Lexapro for the sweats. For the past month I have been feeling bad body aches and tired all the time. I just don't feel good. Got a blood test and it shows no infection. Could there be an interaction with my meds? Should I just stop taking the Lexapro? Not sure what to do. Thank you.
