I'm experiencing this dull pain on the left side of my chest, kind of between the center of my left chest rib and going up towards my left shoulder. It's been happening for about 3 days now, and it gets worse when I lean forward or round my shoulders, but sometimes when I stretch my left shoulder back, it feels a bit better for a while. I dont think its acidity because I dont have issues with that, and Ive never had high blood pressure or heart problems. What could be causing this pain?

Based on your description, the dull pain you are experiencing on the left side of your chest that worsens with certain movements could be musculoskeletal in nature. It may be due to muscle strain or inflammation in the chest wall or shoulder muscles. I recommend taking a muscle relaxant such as **Cyclobenzaprine** 10mg twice a day for a few days to help relieve the pain and discomfort. Additionally, applying a topical pain relief gel containing **Diclofenac** to the affected area can also provide relief. Remember to avoid activities that worsen the pain and try to maintain good posture to prevent further strain. If the pain persists or worsens, it is advisable to consult a healthcare professional for further evaluation and management.
