Now im kinda bothered. its been approx 7 weeks since i start twitching on my left biceps. I also twitch on m eyelids, upper lip, quads, hamstrings, ankle, foot, butt, right biceps, calves, but not as freq as the left biceps. 7 days ago, it became a hotspot and twitched continuously, and strongly( well not continuously. sometimes it will stop for 2-3 minutes) for 5 days and it just stopped like 2 days ago. but it seem like the left biceps is the most active area. now im worried about the localized twitching because I know it is a hallmark of ALS.....
