Try chelated magnesium supplements. :)
"The first symptoms of magnesium deficiency can be subtle. Most magnesium is stored in the tissues, so leg cramps, foot pain or muscle ‘twitches’ are usually the first signs. Insomnia, migraine headaches are also very common magnesium deficiency symptoms.
And if ignored, some of the other more serious symptoms of Magnesium deficiency (low energy, fatigue, weakness, hormonal imbalances, inability to sleep, weakening of the bones, muscle tension, spasms and cramps, abnormal heart rhythm, headaches, anxiousness, nervousness, irritability, kidney stones) can develop."
Excerpt from - Are you magnesium deficient? Leg cramps, foot pain or muscle ‘twitches’ are usually the first signs.
Both hypothyroidism and certain medications for hypothyroidism cause twitching of lips. The symptoms could also be due to anxiety. Contact dermatitis due to coming in touch with spoon, glass, food, tooth brush, plastics, toothpaste etc could be another cause. Low calcium and hypoparathyroidism could be the other causes. Vit B and iron deficiency too should be looked into. Undiagnosed diabetes could be another possibility. Alternatively hypoglycemia too can cause tingling and twitching. Dehydration and electrolyte (sodium, potassium, magnesium and calcium) imbalance too could be a cause. It is difficult to comment beyond this at this stage. Please discuss this with your doctor. A few blood tests to rule out the above mentioned conditions may be needed. Take care!

I have been on synthryoid for about 2 years now without any issues. A few days ago I went to a new PA. I do have an upcoming appt with a doctor on October 2nd. The PA was very rude. I've never had any issues in the past and don't go to doctors. She thought it was stress and refused to run any tests not even a CBC or CMP. Her nurse saw my lip twitch 3 times while asking me questions. I'm not stressed. For once I have a good job and can come home without school or a second job to occupy my free time. My marriage is great and my pets are good. I'm happy. I know stress is and this isn't it. I work at a hospital and Nurses have seen my lip go crazy. It does it literally over 40x a day (I've counted) for over 2 weeks. I'm 30 years,old. I've noticed my lip twitching is triggered more when I eat, move my lips to the right, etc. BTW, my lip twitch is only on the bottom lip on left side. Sometimes it feels numb like there's a gap or my lips are separated on that side when they are not. I've been told it could be iron or to get a MRI for MS..I am just lost and want to be prepared for my doctors appt in 2 weeks. Thank you for your help!
