Well, actually it sounds like fibro to me, but there are many autoimmune diseases that fibro resembles. Yes, twitching, and painful twitching too. Yes tingling all over, and tapping, and sometimes I feel like I'm vibrating especially at night lying in bed. But doc says that's peripheral neuropathy for me. The rest of your symptoms are classic fibro. Severe muscle pain, dry skin, cold, etc. But those are also thyroid problem symptoms too! Have your doctor run tests. Fibros don't just have painful muscle problems. It is sort of an umbrella disease. We often also have IBS, Raynaud's, hypothyroidism, chronic migraines, neuropathy, arthritis, hypoglycemia, TMJ, severe allergies, degenerative disc disease, scoliosis, heart palpitations, lung issues, painful female problems, and I mean for instance in my case allllllll of the above and more. The list is endless. It used to be that to get the diagnosis of fibromyalgia you had to also have something wrong with every major organ. Head, heart, lung, bowels, female organs. It was considered an "umbrella" disease... covered every part of the body.

Try taking Magnesium citrate, read up on it and get a good brand. it's a good idea to take a bottle and then stop to see if it has helped. if you are deficient it wont show up on a blood test as the blood will take it from the rest of your body to keep it's supply.Magnesium citrate sorted out the twitching and cramps for me, it is wort a try

Yes Ive been here for months. I immediately went on b12, magnesium, and other brain nutrients. I also did dry heat sauna, and hot tub. Look for Magnesium calm in the Vitamin Shoppe and try it.

I have the twitching. It started about 6 years ago for me and it gets worse with each passing year. It can be embarrassing. I will drop things without any control. And even my speech twitches

Yep, it was one of my first symptoms. My muscles twitched constantly all over my body for 3 years straight. I only get them occasionally now.
