I m a 26 yr old female. About a month ago I began having swallowing difficulty. Feels like muscle spasms, worse as day goes on. Normal swallow study. I have had other odd symptoms including severe fatigue, inability to focus, stuttering on few occasions during day and just feeling sluggish. My Dr doesn t seem too concerned. My GI dr said it could be signs of ms. But neither dr wants to Perdue testing. I m worried it is ms based on research I did. Does this sound like a possibility? If so how can i get tested if Dr doesn t agree?
