hi noted all your details your symptoms are because of mitral valve prolapse however Mitral valve prolapse causes no problems for most people, so treatment is usually not needed. but in your case most likely severe mitral regurgitation due to mitral valve prolapsehas developed ,it is often benefited from surgery to repair or replace the leaky valve. For people with symptoms of congestive heart failure( swelliing in arms) caused by mitral valve prolapse with mitral regurgitation, surgery is usually the best treatment. but if there is no mitral regurgitation is present on echocardiogram, symptoms of mitral valve prolapse rarely pose any risk. The best treatment for each person may vary, but can include: Exercise Pain relievers Relaxation and stress reduction techniques Avoidance of caffeine and other stimulant so your treatment and my suggestion fully depends on report of your 2d echo you can follow the treatment after considering the echo report yourself thanks
