Hi,it was really, really tough for me to survive the waiting to 14:00 (CET). At first I said to doctor my concern about ALS and expected something like "no way"...lol, he said "hopefully not, we will see".The first part was OK, then came the needles. My anxiety was terrible, then he put the needle to my thumb muscle area and there was silence from the reproductor. He continued and did 3 muscles on my right arm, my left deltoid (which twitched pretty much) and then my leg and my TWITCHING foot..all was clean!He said very important thing to me, that the twitching in my foot isnt fasciculation, but "action potentials". He said true fasciculations is wawe-like movement through many muscle fibers with typical pattern. Generally he said twitching itself isnt always fasciculation, however its seen.He said this is typical idiomuscular hyperexcitability and I should check my Ca and Mg ionts, so no way to know it from simple blood test.Anyway, no denervation!Laurent: I asked especially about the foot thing and was told that this muscle is the most "overload" muscle, since it supports your weight and bone structure, also we were right in our guess. Said its nothing special to twitch here and if some muscle should twitch, that would be this one.
