Hello guys I am 20 years old. I am a little hipochondriac but I am really worried that i might have ALS. Many doctors dont believe me i have all these symptoms and that i might have als. It all started with weakness in my right leg and right arm which progressed a little.But it doesnt go away for 2 weeks now, My right arm is really shaky when i hold something because some of my muscles begin to shake. I still have power.... I test my power i have it but my arms feels so exhausted. My right leg also feels the same waty. The whoel quadriceps (mainly the quadriceps ) feels so stiff and weak that also sometimes shake when i do precise movements but when i walk i feel it weaker and when i climb stairs i really feel it like its gets tired faster than the left much faster. I also had some symptoms of dysphagia and sometimes i fell neauseas when i lie down but this could be stomach problem or anxiety problem. My question is what are the chances to have ALS ? I already did na MRI which was clear but ALS isnt seen on MRI :(
