I'm just going to ask this as it's what I'm worrying about. I am on my feet every day but have been for years, I have a dog that I walk, again, for years, I read on lots of websites that I know I shouldn't of looked on but too late I have, that sore muscles are a symptom of early als along with twitching. I'm struggling to understand how 2 completely different illnesses can cause the same symptoms? Xx
