Hello , every night since a month ago, I get this internal vibration/tremor feeling ( especially in legs) when I'm about to fall asleep. I also hear this weird buzzing sound. The feeling stays for about 5 seconds, then leave for a sec, then starts again for 5 , ect... A few times, it even happened as I woke up. I'm having huge MS fears. Is this internal vibration/buzzing sound at night something that happens in anxiety? Any experiences?
