I have been diagnosed with Undifferentiated Connective Tissue Disease and Hypothyroidism, but I am also having symptoms that do not fit into either disease. I have been trying to narrow down the possible causes so I can have an informed, intelligent discussion with my doctor, and I have been researching symptoms like crazy. One disease keeps popping up with alarming regularity so I wanted to ask the opinions of people who have the disease whether it is my imagination or if I should ask to be tested for ALS. I have muscle atrophy, muscle weakness, muscle spasms, burning in my toes (sometimes in other parts of my feet and sometimes in the back of my right hand), achy legs, difficulty standing after I've been sitting for a while, frequent choking, chronic nausea, loss of appetite, I have had esophageal spasms, sometimes it feels as if I can't get my lungs to work. All in all, it has been a very unpleasant ordeal.
