It sounds distressing to have left shoulder pain radiating to your head along with dizziness and anxiety. These symptoms could be related to muscle strain, nerve irritation, or possibly issues involving the neck or heart, so it’s important to get a thorough evaluation.

• Avoid repetitive shoulder movements that worsen your pain and try gentle rest.
• Apply ice or warm compresses to the shoulder to reduce discomfort.
• Over-the-counter pain relief like paracetamol or NSAIDs may help, but consult a doctor before starting any medication.
• Since dizziness and radiating pain can sometimes signal more serious conditions, please see an orthopedic specialist or neurologist promptly for a detailed assessment.
• If you experience chest pain, shortness of breath, severe headache, or sudden weakness, seek emergency care immediately by calling Apollo Emergency at 1066.
