This is strange, but I must ask. I started on 5 mg of Lexapro a little over a week ago. I woke up yesterday with horrible jaw pain on one side and there seems to be a knot on the inside of my lower jaw and down in the front of my neck. Also, my mind is racing, almost compulsive. I wake up with a song of all things, in my head and that continues for awhile. Also, if I cannot think of the name of something, etc, it drives me nuts until I figure it out. Now, I am really starting to think I've gone crazy!!! Could this be side effects of the Lexapro? My doctor told me I could feel worse when I first start taking it. I also take Trileptol which is a form a Lyrica. Do not know if it could be from that med too!Am I just going crazy or what?
