Bygrace,
I have joint pain quite frequently too. I take Zoloft instead of Lexapro. I am always having some kind of new pain in a different area. Legs, arms, chest, back, neck, you name it. I think it may be caused from the muscle tension associated with the panic and/or anxiety. I have been to the doctor about this and he didn't seem to think there was anything wrong. i just have to keep myself convinced that I dont need to worry about it. I catch myself tensing up alot, like clenching my jaws for example. Later on I notice that they are sore from it. Sometimes when I drive, I find myself clenching the steering wheel so tightly that my knucles are white and my forearms are aching. Do you think your pains might be from things like this? It took me a while to realize what was causing mine. Good luck, and hang in there. :) Sammi
