Hi all: I'm sorry to post but really hoping for input. A few week who's, I started having blurry vision and headaches. I eventually went for a brain Mri which came back clear. I was then out on medicine for anxiety. A few days after I started the medicine, I began experiencing major cramps in my lower leg muscles. I feel cramps/stuff after walking up stairs and even when I lay in bed. From what I read online, muscle cramps is a major sign of muscle weakness. Should I push for more tests, as I am now worried I have als. Thanks!
