Hello,
You experienced
sharp pain in the neck radiating to the chest while breathing. Don't delay and get clinically examined by a GP / cardiologist, he will ask you to get few blood tests, imaging tests, etc., done to evaluate the cause of your symptom. If a heart issue is detected, it will need urgent medical care and will be treated accordingly.
If not, then other medical conditions that can cause similar symptoms will be evaluated and treated. Other medical conditions that can cause similar symptoms are
arthritis,
muscle pain, muscle spasms associated with
neck pain that can radiate to the muscles of the upper back and even the chest, C4
radiculopathy, spacing problem at C3-4, etc.
Stay away from any addiction. Avoid smoking, alcohol or drugs. Switch to healthy lifestyle (regular walking) and healthy eating, take home made food. Avoid taking packaged and processed food, trans fat, refined flour, etc. You should take home made fresh food made in olive oil.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
