Hi! I understand how distressing these symptoms can be, and I appreciate you sharing your concerns. Based on what you've described—episodes of feeling like your breath is "stuck," normal heart tests (except sinus tachycardia), and a history of health-related anxiety—it’s possible that anxiety, hyperventilation, or mild airway reactivity could be contributing to your symptoms. Possible Explanations for Your Symptoms: Anxiety-Induced Breathlessness: Anxiety can cause breath-holding, a sensation of air hunger, or even a "stuck" feeling in breathing. Sinus tachycardia (fast heart rate) is commonly linked to anxiety. Inderal LA (propranolol) helps control heart rate and anxiety symptoms, which is why you felt better initially. Vitamin Deficiencies (B12 & D3): Low B12 can cause nerve-related symptoms, including breathlessness or a sensation of "air hunger." Low D3 can contribute to muscle weakness and fatigue, making breathing feel harder. Airway Reactivity (Possible Mild Asthma or GERD): Since your mother has mild asthma, there may be a genetic link. Silent acid reflux (GERD) can also cause a choking sensation or breath-holding episodes, especially at night or early morning. What You Can Do: ✅ Continue managing anxiety – Meditation, deep breathing, and therapy can help. Cognitive Behavioral Therapy (CBT) might be useful. ✅ Correct B12 and D3 levels – Your doctor may recommend supplements for these deficiencies. ✅ Monitor your breathing patterns – Try slow, controlled breathing when anxious. ✅ Check for silent reflux – If you have acidity, bloating, or throat irritation, GERD could be a factor. Avoid late-night meals and spicy foods. ✅ Rule out mild asthma – If you feel chest tightness, wheezing, or persistent breathlessness, a lung function test (spirometry) can help confirm it.
