Doctor, I occasionally experience very mild pain on the right side of my abdomen. In addition, I have a feeling of heaviness in my throat, tightness and pain in my upper abdomen and chest, and sometimes a sharp, stabbing pain in my upper back, directly behind the chest. My abdominal ultrasound report is normal. Could you please review my reports and advise me on what I should do next? Based on my reports and symptoms, what could be the possible cause of these problems? What further investigations would you recommend, and what would be the appropriate treatment? I would be grateful for your medical advice and guidance.
