Most people have back problems .So I guess people with ALS can have non related back pain. As I said before Just because we have als doesnt mean we cant have artiritis cancer strokes heart disease ackes pain need eye glasses Get my drift! People on this forum think that every thing they feel is ALS related. If I get nausea and vomiting would it be a symptom of ALS NO its a virus If I get a earache is it ALS probably not I think the ones here that have ALS have the same symptoms are mainly Atropy weakness fatigue twitching fascis falling dropping thinks breathing problems swallowing eating chewing problems and maybe a few more . I find my symtoms arevery similar to the others here with ALS So not all things we feel at one time or another is ALS related Pat
