I have seen several Neurologist each one says something different seen three at Mayo. The one here said its my heart my Cardiologist says it ain't my heart. I do have several bulging disc C3,C4,C5,C6 and something going on at T10,T11. They tell me they dont think thats my problem. My family Dr keeps saying nephropathy. I have to agree it is something to do with my spine but all the test is not showing anything to warrant a diagnosis. I have seen Neurologist, Lung Dr, Cardiologist, Gastrologist , Pain Dr. They can not come up with a diagnosis. The Drs at Mayo couldnt find any answers they told me I was in the 10 to 12% of the unknown. It doesnt matter what position I am in the pain and pressure comes and goes. The pressure on my chest is constant and gets worse with any activity . The sharp stabbing pains hit at anytime no matter what I am doing. Laying down can cause it to get worse but getting still and resting it will ease up. I do know lifting makes my chest hurt as well in between my shoulder blades. I have asked about a pet scan on my heart and a Hyda scan on my bladder and was told I didn't need one.
