I have had anxiety for almost 5 years now. Just when I think I have exprienced every wierd symptom something new starts. Does any one have this? When i am trying to fall asleep I will have a jolt/ single muscle twitch. It's not like when your eye twitches repeating it's just a quick jolt/twitch. Like my hand with just twitch once real hard. It will do it once and then when I am about to sleep wham my leg or something else will do it. Also when I am sleeping I will jolt up real quick. The same feeling you get when dreaming of falling exept I am not dreaming I just jolt/twitch awake. Like I said just a hard single twitch, not the fluttering twitches. Just started about 4 weeks ago and of course i am thinking the worse like ALS or MS. Did have an MRI about 4 years ago, because of other wierd things and they saw no signs of needing further test for MS. But of course with anxiety we always think the worse.
