in Recent months I have experienced extra fatigue, occasional dizzy spells, some shortness of breath, bruising for no apparent reason and lasting longer than before, leg cramps during the night and now today, some bleeding of my gums... had echocardiogram 2 weeks ago as doc heard new heart murmur. Echo came out ‘fine.’ Apparently it showed slight enlargement of the muscle. Was told not uncommon for my age. No worries. My symptoms are still concerning. I have no energy. Thanks for your input or suggestions. Email address is YYYY@YYYY
