I don't think people believe antidepressants are a cure for everything; however for this neurogenic and and other brain related conditions, for some reason (?) the antidepressants calm down the nerves and minimize or reduce the symptoms.
CASE IN POINT: I went off Lexapro last spring, after being on it for years.......I didn't think I needed it and I seemed to be fine. However, in the fall, this itching came and was very intense, so much so, that I had to go to great lengths to trouble shoot it. After I tried many things and read that folks were being treated with antidepressants, my first thought was to go back on the Lexapro and BINGO....my symptoms were reduced significantly and only after 4 days. I am using the TKAL cream at night, because I feel the symptoms more so then than during the day.......but NO MORE ICE PACKS......My guess is when I am back on the full 20 mg. I won't need even the TKAL cream. Still seeing the neurosurgeon this week.
