Please can someone advise me on this constant muscle twitching that I have been having for nearly one week now. I am an anxious person and have a big health worry with my son who who is quite ill with a chronic illness. This past week I have had this twitching all over and I am so worried that I have something serious going on. This morning I have woken to a facial muscle just below my lip twitching around every 5 to 10 seconds, driving me nuts to say the least.I googled it and it said that facial muscle twitching is a sign a of MS. So now I am scared. I get even more worried about my health because I am a carer to my son and he needs me. I have been taking magnesium supplement only for two days now to see if that helps. Has anyone else had this? I have not been the DR yet as I didn't want bad news over Christmas but now i'm thinking I want to go whatever he outcome.
