What Causes Leftsided Shoulder and Front Left Neck Pain After Eating?

Angina can cause episodes of pain and aching radiating across the chest, arms, shoulders and jaw, and eating a heavy meal can trigger it, according to the Heart Foundation. Fatty deposits that build up in the arteries cause angina.

Bouts of angina occur when oxygen and blood can't flow properly through to the heart, states the Heart Foundation. Symptoms include tightness or pressure in the chest, difficulty breathing, and heaviness, numbness or tingling. Many people experience angina attacks during exercise. Lifestyle changes, such as diet and stress management, as well as medications, including nitroglycerin, beta blockers and anticoagulants, can treat the condition. Surgical procedures, such as angioplasty and coronary artery bypass, also treat angina.
