I would put money on the fact that I have MS. The numbness I have had in the past and at the current moment in my finger tips, the muscle weakness in my leg, and now this... loss of vision in my left eye. My symptoms sound like optic neuritis... vision worsens in bright light/ sun light, pain when I look side to side, and just an overall blurry feeling that makes me feel tired and that I am in a cloud. I dont want to have MS, I have seen my brother struggle with it for years, thank god he is doing well now. But I want some explanation as to why these crazy things are happening to me. MRIs were clear. But I am 20 years old and I think I am too young to be falling apart! I just want some answers and try to make these things better... walking is my main problem. My muscles in my left leg get so weak. And now I think my right leg is so tired from doing all the work that they are both getting weak. I find myself falling forward or backwards when standing because my legs are just so tired. Its like i'm falling and my legs are catching me everytime I take a step. And god forbid I crouch down, I cant get up on pure leg muscle alone... I have to grap on with my hands and pull myself up. I AM 20 YEARS OLD! haha I dont think this is normal... I am in relatively good shape and was always involved in sports in school. Now I have a 3 year old who runs the show and I certaintly get my share of exersize... I just dont get it!
