HI MY DAD HAD HEART SURGERY FOR A BICUSPID HEART

HI MY DAD HAD HEART SURGERY FOR A BICUSPID HEART VALVE AND HAVE STRUGGLED WITH FATIGUE FOR A WHILE AND I HAVE FLUTTERING IN THE CHEST OCCASIONALLY. I AM CURRENTLY DIZZY AND LAST NIGHT HAD SHORT BREATH....I AM WEAK RIGHT NOW ALSO... I DO GET MUSCLE SPASMS BUT NO HEADACHES. I DO RANDOMLY GET SHARP HEAD PAINS BUT NOT FOR LONG. WHAT COULD THIS BE? WHAT DO YOU RECOMMEND? ARE THERE DOCTORS THAT HELP FINANCIALLY FOR THIS?
