I'm sorry to hear you're experiencing pain on the left side of your chest and in your left arm. These symptoms can sometimes be related to serious heart conditions, including a heart attack, and should be taken very seriously.

Here’s what you should do immediately:

• If the pain is severe, sudden, or accompanied by other symptoms such as shortness of breath, sweating, nausea, dizziness, or weakness, call emergency services right away (Apollo Emergency - 1066).
• Do not ignore these symptoms or try to self-treat without medical evaluation.

Possible causes and relief:

• Chest and arm pain can be caused by angina (chest pain due to reduced blood flow to the heart), which may be related to heart conditions.
• Medications like calcium channel blockers (e.g., Cilnidipine) are used to manage chest pain and high blood pressure by relaxing blood vessels and reducing heart workload, but these should only be taken under a doctor’s guidance.
• Lifestyle changes such as reducing salt intake, regular physical activity, and weight management can help improve heart health.

Important: Because chest pain can indicate a life-threatening condition, it is crucial to seek immediate evaluation by a cardiologist (heart specialist) or visit the emergency department to rule out a heart attack or other serious issues.
