Forgive me ahead of time if this isn't related to COPD, but I hoped you could help since shortness of breath is involved with my symptoms.
For many months I have been experiencing dull pain with each heartbeat in a specific location deep in the center of my chest, about 2 inches below the bottom of my throat or 2 inches below the interior of my shoulder blades; sometimes it feels like blood pools in that area and pressure builds up in my upper chest and head. I have also experienced isolated/occasional heart palpitations that occasionally cause me to have near-fainting and I was told these were early beats and not to worry about it. I've also had symptoms of general lightheadedness, as well as shortness on breath and vision fading during heavy lifting. In the same spot as the painful heartbeat, if I'm very relaxed and at reast (heart rate is slow), instead of pain with each beat, there is just a dull heaviness or choking sensation in the same spot. I have none (never before) of the palpitations or lightheadedness before this other symptom started.
I've had routine blood tests including SED rate which was 0, chest xray, echocardiogram, plain treadmill stress test, overnight sleep study, EKG, Holter monitor.
Only thing that showed up was the early beats on the Holter, as well as mild Pulmonary and mitral regurgitation on the echocardiogram.
Are the tests I've had sufficient to rule out a serious problem with certainty? Is there any other test I should have?
Note: my medical history is remarkable for an orbital roof 3.5 cm bone tumor which is stable but causes headaches.
