Question I'm feeling extremely worried and tense since April, and it's affecting my breathing. I checked with my GP, did all the tests like thyroid, sugar, hemoglobin, and CBCthey're all normal. My ECG showed sinus arrhythmia. I'm on a tapering dose of Metxl 12.5 once a week after consulting with my GP. However, I'm still experiencing these anxious episodes where my pulse suddenly shoots up, and I feel hot, sweaty, and shaky. Sometimes, there's a headache, and I can even feel my pulse in my head. My heart races, and I get left arm and shoulder pain, along with nausea and loss of appetite. I rarely feel any chest pain, possibly due to anxiety, but it's mild. I've tried to calm myself, but this seems to have become a constant part of my health. Should I get another heart check-up because I did an ECG in June, or is this just anxiety? I'm really confused about what to do next.
