@frking I'm assuming you mean a cardiac catheterization, used to study the various functions of the heart? More of a final diagnostic procedure to rule out diagnosis.

Thankfully your heart is functioning normal thus far. My daughter had a heart ablation as a teenager and went through the whole wearing heart monitors for years. It was annoying to her and I'm sure annoying for you as well.

There is a fear when experiencing abnormal feelings, senses and functions like you are experiencing that are unexplainable through test results. You are doing all the right things by going through the motions of ruling out any major malfunctions. I'm sorry you've been at it for 6 months.

Have you read up on Central Sensitization Syndrome (CSS)? There has been talk of it through Connect and this thread. I'm certainly no doctor, but you really do display the various wide range of symptoms that CSS can cause. When I wasn't aware of my CSS diagnosis, I went through a rough patch of diagnostic testing on most of my body, all of which came back normal except for Small Fiber Neuropathy. I had concern about my organs as well from digestion to heart and lungs.

Anyhow, CSS may help explain your unexplainable symptoms such as smelling burning wood, pressure in your chest, pinching pain, perspiration and shortness of breath.

If you're interested in learning more, here is a video from Dr. Sletten of the Mayo Clinic, Jacksonville, FL explaining the science behind CSS and its course of action:

I wish you good luck on your final heart test. Keep thinking positive. Do you mind letting me know what you think of the video? I'm curious...will it connect for you? Have a wonderful day! 😊
