I am really scared that I may have MS. I'm a 19 yr old female. My symptoms started last year. I've always been a anxious person but, I felt funny symptoms like feeling really unbalanced, and dizzy, spasms, jerks, tremors(mainly in my hands), And a weird flare like light in the corner of my left eye. Now I feel a bad pain pretty much all over my body, really bad in the back of my head and upper back... My arms get really tired holding up stuff and really sore arms. At first my doctor thought anxiety. But I went back and she said that my left leg the reflexes weren't as good as my right. I have an appointment with a neuro and I'm petrified! I'm really hope for the best but, I have my doubts. Could it be anxiety or maybe depression? I had blood(twice.) done and an x-ray and an MRI came back good...should I be worried?
