I had surgery last Tuesday. The following surgery after a nipple spearing mastectomy on my left breast. On Thursday I started experiencing some lightheaded when move my head to turne to the sides, I have to blink few times to see when reading, I skeep words when writing a sentence so I consciously have to double checkand, feel very distracted when trying to do things. Should I think this is due to the widraw of lexapro a week ago in spite of following my doctor s instructions or can it be something else?
