I started Lexapro 11 days ago for severe anxiety and panic. So far, no relief. I am still having my anxiety symptoms of numbness, tingling, twitching, weakness, and shaking, in my arms and legs and face. I was really hoping it would help with the physical symptoms by now so I can stop worrying about whether or not I have some neurological disorder. My doctor told me all my symptoms are from severe anxiety and stress over the last 6 months. It would be nice to feel normal again. Does anyone know how long I should wait before I know this drug isn't working?
