Hello,
I am sorry to hear about your insurance problem. This can be a challanging issue and occurs more commonly than you probably realize.
Does it sound like my increasing concern is warranted and would you suggest I seek further tests now?
It sounds like you are having symptoms that could be cardiac related, although a component of your symptoms does not. With some risk factors (HTN, increased cholesterol, family history), you should probably see someone sooner than later. It situations like this it is our job to prove that it isn't your heart causing the symtpoms and this usually takes a few tests. Early heart problems are sometimes reversible and waiting can lead to damage that is not reversible. You can work with your doctor to try to order the most appropriate and least expensive modalities available.
Good luck and thanks for posting.
Can you afford to pay for a visit to a cardiologist? The tests are expensive, but talk a cardiologist about your insurance problem. I have CAD, and your symptoms sound like heart problems to me. Getting symptoms with exertion is one of the signs. Also, they are increasing, and you have fatigue. I don't want to scare you, but you really need to see someone. I would not bother with an internist, because they will send you to a cardiologist. You are young, but I had a friend drop dead at 42. Don't take a chance. If I can help you, I would be glad to give you my e-mail.
