I just started taking lexapro (5mg) for anxiety and problems with my moods and lack of motivation. The first day I started getting a weird sensation in the back of legs that spread to all of my lower legs, they felt kind of numb or tingling like when they are falling asleep, but I was up and walking around doing laundry. Has anyone else experienced this side effect before? This has never happened to me, so I know its from the lexapro. Thanks
