Thanks for replying...I don't believe I am similar Lime, but I do have symptoms that are obviously concerning to me...Mind you, I've had 2 clean EMG's on the affected area and the Neuro+Dr's have chalked it up to some kind of muscle injury....however, I am steadily losing muscle on the left arm...whole arm is thinning out and fasciculates on and off in fact, so I don't know if a tendon tear could cause something like that (continuously).....The EMG's were done on the affected arm so I can pretty much say no to ALS, but I guess the fear lingers on in the back of my mind and I keep waiting (not wanting) for it to get worse.
