 Yeah, this is something that could be something completely innocuous, but it could also be something more serious. This is one of the rare instances I would say I can give you advice over the phone. This is something that you need to see your doctor. Of course, I'm a cardiologist. If you have concerns, you're welcome to make an appointment to see me. I like to answer questions on the air, but there are times when I have to resist because this could be something very, very simple.
