No one here can diagnose you. My advice is to go see your doctor and see what he or she says. If you are having anxiety issues, then be sure and get that treated. Please tell your mental health professional that you are having anxiety about
having ALS and or MS based on some symptoms you are having.
I am very sorry you are not feeling well, and that you are anxious about it. I hope you are feeling better soon and get some answers to these issues.
