Question: After months of chest discomfort/pain that seems to be getting worse by the week, I found out today that the most recent tests (ventilation scan and chest x ray) have come back normal. Certainly a relief, but still a mystery. My doctor is convinced that this is not a heart issue. My question is whether or not a ventilation scan and x ray would potentially fail to register something that could create chest pain (pressing across breastbone, sharp cramping up left side that can last for hours, and sometimes what feels like a burning upper left side). No fever, no swollen glands, no cough, bloody or otherwise; I am not obese, and maintain a plant-based diet. No medical issues every, really. Have managed with muscle/tendon problems pertaining to my profession for decades, but this feels completely unfamiliar. Nothing I do seems to bring it on, and there seems to be nothing I can do to alleviate it. At its worst, the resulting fatigue is overwhelming, and it is making regular tasks in my daily life difficult. Tests for later this month include CT scan, bone scan, and echocardiogram. Blood taken today for RF, and MRI of the back of my neck is a possibility mentioned today. I believe my doctor thought it might be lung cancer (although he didn't say that outright), so he was pleased with the results today (as was I!) but until today, since I'm a new patient of his in the last three weeks, I don't think he was completely aware of the amount of discomfort I'm in. In your opinion, could this be some kind of tumour? I do find the progression of the symptoms alarming, and I know that the CT scan should reveal more, but I look forward to hearing your thoughts. Thanks.
