Yes, it is possible to have twitches as your first sign. Possible, but highly unlikely. For every rare story like this, you will find hundreds more on this forum in which the twitches were attributed to bfs.Also, I went through that poor girl's posts. It seems that she was falling down about 6 months into it, indicating weakness. At what was about 7 months her reflexes were off and if I do recall she also posted about slight hand atrophy. We also don't know the full story. We don't know if she chose incompetent doctors who didn't give her a thorough exam at first due to her very young age, etc.I think the consensus is 6 months with no weakness or atrophy and you can be pretty sure it's benign. The younger you are, the less likely it's als. I believe you're still a teenager, right? My dear I can assure you that you're fine. I used to twitch here and there in high school too and decades later I'm still here. Talk to your parents and see a therapist. You have a better chance of getting an aneurism or cancer than als, yet you don't worry about that, do you? So many people twitch and it means nothing.Please also be careful posting things from other forums here. It only causes worry and the scenarios are so rare, that it does no one any good. Take care.
