I think the valve problem is causing your chest and neck going on. Low blood pressure can cause dizziness.
Has your doctor recommended a schedule for repairing your valves?
I had my mitral valve repaired in 2007. It is a serious operation, but one that must be undertaken in some cases.
Doctor called. Seems there is an infection going on and other tests pointing to possible thyroid problems...time will tell
That could be good news, in a time of bad news. I believe thyroids can cause heart problems, and are responsive to drugs...not sure that's what you've been told, but sounds like a possibility.
