Hey Jerry...I am gone for a few months..come back and you fell apart....It amazes me when someone who is active and physical fit has these type of medical problems......if you were over weight, smoked and just sat around it would be one thing but being in the shape you are.....it does not make sense..
Your cardiologist Iam sure must be top notch.....if in a couple weeks you are not better...make an appt with another board certified cardio for a second opinion.....the heart is NOT something to ignore....trust me I know.
I hope your son is doing ok...that surgery sounds SOoooo painful.
By the way did/does your doc know about you going diving???? I would think that is not something to do with heart problems....
Take care...my thoughts and prayers are with you and yours....
