Is breathlessness and chest pain a known anxiety symptom? I've had a negative covid test, clear chest xray and various blood tests at the hospital. Also my oxygen levels were never below 96% I had a blood gas test and the doctor did say it was borderline so to rule out a blood clot I have to go back on Monday for a CT scan. But I have had really bad anxiety on and off for years, specifically health anxiety. Just wondered of breathing can be an actual anxiety symptom?
