Hi Stan, I haven't tried Lexapro, but am on two different anti-depressants.
Both are double dosed- Paxil Cr 25 mg. and Wellbutrin XL 300 mg. They help a lot with depression, but not completely gone. RSD affects the Limbic part of brain that controls moods like depression. Also, it is known that anti-depressants help with nerve pain. Hope this helps. Loretta
