First off I need to say I didn't have any of these problems until January 2014! I had been having some anxiety issues, and was giving a script for Ativan (lorazapam) I took this medication for about 2-3 weeks. It was only 1 mg once a day, but I was taking it daily for panic attacks. I would notice if I skipped a few days I would get nausea, and throw up with a bad headace. So I took it a few more days then finally said enough is enough. That is when all over body twitching started 24/7....... Then I had some really weird feeling in my upperarms. They feel like how your muscles feel if they have been worked out to fatigue. It kinda is uncomfortable beacuse they feel heavy. They have a vibration inside like the muscles are shaking very light, but its super annoying. I have tried magnesium it didn't help. I also find its worse when the weather is snowing or raining. I also have been getting charly horses in my neck muscles, and my tougne feels swollen. I have went to the ER they said I was fine after giving me a hand eye cordination test. Been to my Dr close to 8 times. I have had a ANA test, Reactive C, CBC, Executive panel, hormones, vit d, vit b12 (high 972)..... Everything always comes back fine. Three months later, and I am still dealing with this. Its not normal. Dr's tell me its anxiety. I know how anxiety feels. I want a MRI, but they say no. I worry about MS or ALS. I am 32 yr old female, and healthy weight. I don't smoke or drink.
