Guys--it's time to stop answering dear Bob. He's not listening to anything anyone says. Stop feeding would be my suggestion.
Bob: Asked and answered. You don't have atrophy--the doctor would have seen it. Swelling is NOT a sign of ALS. Period. It's just NOT. It's a COMPLICATION of issues in limbs that are UNUSABLE or VERY weakened to the point of not being used.
Seriously--get a grip, and really, with all the best intent I say this: Please see a doctor about your health anxiety before you truly do become ill.
Swelling in the feet is never normal--but it can have very, very benign causes--and luckily for you, ALS is not one of them.
Atrophy is ALWAYS ALWAYS preceded by WEAKNESS. Always, because the weakness in ALS is caused by the nerves no longer connecting to the muscles, hence, the muscles weaken and DIE. The body reabsorbs the muscle that is no longer being used--which is what Atrophy really is. It's DEAD MUSCLE, for all intents and purposes.
