Normal Body Muscle Muscle Twitches All Over My Body? Is This Normal?

Muscle twitches all over my body? Is this normal? - normal body muscle

When I was sixteen years old, I developed an anxiety disorder (I've always). I was terrible panic attacks every day several times a day, and that he had muscle spasms in the stomach (like when your eyelid spasms, but) in my belly. Two years have passed and I still have contractions, but not just in my stomach, I get around now by chance and random places on my body from head to toe. Is this normal?
I had contractions per day .. Sometimes during the day I will some muscle contractions ... (especially in the stomach, but also in the legs, arms, hands, face, legs, everywhere I would imagine, given .)... Why is this so? I hear it's a potassium deficiency, but eating a banana a day (a milkshake) soo, what would it be? What is fever?

ohh and I also like tingling (like when you chills), but on the side of the arm, leg, and sometimes next to my head ... Why is this so?
