I have mild chest pains on the right side of my chest. The upper section of my right arm is a little sore also. I was recently diagnosed with MVP. I had an EKG, a stress test, and an Echo about a month ago, and eveything looked good(minus the MVP). Normally I only get palpitations caused by MVP, but the fact the I am feeling some pains is concerning me. They have been coming and going for the past 4 hours. It brought on a mild anxiety attack, but I took a Xanax and that subsided. I have never exprienced pains that lasted this long. I am not having any trouble breathing, and I am not sweating or dizzy. I m not sure what is wrong with me, and do not want to ignore it if it could be serious. Please assist!
