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.
