Hi. I'm a 45 yr old female. I have been suffering with weakness since 2014. It's now gone into my legs. I have to sit often and if I do walk to much I'm in so much pain the next day. I'm having breathing problems, and problems clearing the phlegm from my throat. It feels like it's stuck in my nasal. I also have trouble swallowing, it feels like it wants to go into my nose. My neck, stomach, and back muscles are weak. I have pain at times. I feel very off balance. I have no idea what's going on, but it's getting worse. My doctors don't have any diagnose. I'm waiting to go to Emory in a week.
