Slight pain on the left side of the chest with a normal ECG (electrocardiogram) and blood pressure of 100/70 could be due to causes other than heart problems, such as acid reflux or musculoskeletal issues.

🩺 Possible Causes

• Acidity or acid reflux can cause chest discomfort that may persist despite initial treatment.
• Muscle strain or inflammation in the chest wall could cause pain, especially if the injection given was a pain reliever like Zerodol (aceclofenac), which targets inflammation.
• Less commonly, other non-cardiac causes like anxiety or lung-related issues might cause similar symptoms.

⚠️ When to Seek Urgent Care

• If the pain worsens, spreads to the arm, neck, or jaw, or is accompanied by sweating, shortness of breath, or dizziness, seek emergency care immediately.
• Persistent or worsening pain despite treatment should be evaluated further.

🩺 Next Steps

• Follow up with your doctor or a gastroenterologist if acidity is suspected to adjust treatment.
• Consider evaluation by a cardiologist if symptoms persist or new symptoms develop, despite a normal ECG.
• Keep a symptom diary noting triggers, duration, and severity to help guide further assessment.
