... shortness of breath. Also my throat feels like it's swollen when I swallow. During the day I am mostly ok. During the night it's really bad, can't get enough sleep. Saw my doctor, she did bloodwork cardiogram, echocardiogram, chest xray she said other then my cholestorole and LDL being high all looks ok. Now I am going to see my cardiologist to see what he has to say. How long will this last? Any other experiences out there with Lexapro doing this kind of thing?
