I'm feeling really anxious because I've had this mild chest pain between my right breast and the center of my chest for the last 15 days. It happens when I twist my shoulder to the right. I started taking Pantoprazole 40 and Myospaz Forte as recommended by a local doctor three days ago, but the pain is still there. What should I do now?

It sounds like you may be experiencing musculoskeletal pain in your chest area. In addition to the medications you are already taking, you can try taking a nonsteroidal anti-inflammatory drug (NSAID) such as Ibuprofen 400mg every 6-8 hours as needed for pain relief and inflammation. Additionally, applying a warm compress to the painful area and practicing gentle stretching exercises for the chest and shoulder muscles may also help alleviate the discomfort. Make sure to avoid any activities that worsen the pain and try to maintain good posture. If the pain persists or worsens, it is important to follow up with your local doctor for further evaluation and possibly imaging studies to rule out any other underlying causes of your chest pain.
