Mitral Valve Prolapse. Next. tnq!

Hi, Had occassional palpitns frm past 2yr. In jan21 chest discomfort felt freqently. So in feb21 did full body checks & things are normal (ecg, echo are normal). Later in aug21 started some moderate stomach pain & did abdominal usg, ct scan results were normal. In dec21 heaviness/discomfort in chest increased so again did ecg(normal), echo found Mild MVP with trivial MR. Dr suggested to take betacaptr20. Now I feel symptoms like -Discomfort, heaviness in chest while resting. Pounding hrt beat if I do some extra work. -Also now having pain in sternum area while pressing that area & while rotating my neck, shoulders. -Occasional stomach pain. So pls suggest: 1. Does mild MVP MR cause these symptoms or anything else to be ruled out. 2. Is there any link btw stomach pain & MVP. 3. Does MVP cause weight loss(lost 6kg in 6 months) 4. Does MVP cause sternum area pain. 5. Feb21 Echo was normal but Dec21 Echo found Mild mvp,mr. Will MVP develop in 8 mnths. 6. What steps to be followed next. Tnq
