(Riggz10) To answer your questions, yes, I did notice that my legs cracked when I stood up, etc., but I'm not sure if it was ALS-related. I experienced a lot of pain in my legs during the onset of my symptoms - it felt like my shins were about to cut through my quadriceps while I was standing, if that makes sense. I also had migrating burning pain in my legs, arms and hands, although my doctors are unable to provide an explanation for these symptoms. I can still walk on my toes, but not on my heels because my ankles are too stiff. I wouldn't necessarily compare my situation with yours because all of my neurologists have said that my presentation was very atypical. I think in your case, the longer it takes your doctors to figure it out, the better it is for you (ALS-wise, at least).
