Well I will finish my 4th year with BFS in June. But somehow last months the twitching seems to be worse and stronger, more confined to my upper arms and thigs. I flex my arm and it starts to tremble from abundandant fasciculations, then suddenly my thigh will twitch 5x times...etc. I have never had this. It was always like twitch here or twitch there and now it seems there is increase in them. I do not have any hot spots (nothing goes 24/7) rather than spots that twitch pretty often for short periods of time, like 20x per hour.Especially my biceps and triceps twitches are pretty strong and even after four years its quite new for me..its strong, moves clothes..and scare me.
