I've very mild mvp. Once in a while, i'll get pulls and tugs on d left side of my chest near d heart. It will sometimes last a few hours. Is there cause for concern? Wat wld usually cause these tugs? They come on suddenly

Not likely from MVP. The symptoms your describing are not likely to come from your mild mvp; most likely muscle spasm (intercostal--muscles in-between your ribs). If you are physically fit/active and able to exercise w/o difficulty, then it is even more reassuring that it is not heart related. Good, deep breathing exercises, stretching/chin-up type of activities may help. If persistent, consult doc. Good luck.
