Pain Causes
For an understanding of the nature of pain (pain causes), it is essential to understand that the pain sensation is often found in a 'dermatome region', and not in the damaged or diseased body part or organ. These relationships are often involve damage or disease to an internal organ projecting the symptom of visceral pain on to an outer region of the body.
A well-known example of this is the relationship between the heart and the neck – hence the acute pain in the arm experienced during a cardiac arrest.
Other examples of these relationships are as follows:
• Physical trauma can be felt in the jaw, the eye(s), the neck and the breast
• Severe temporal arteritis in the jaw
• Glaucoma in the eyes
• Cancer in the head, the back and the breast
• MI, GERD, hiatal hernia and pulmonary embolisms in the chest
• Hepatitis, gastric cancer, ectopic pregnancy and urolithiasis in the abdomen
• Deep vein thrombosis and peripheral vascular disease in the legs
• Inflammatory bowel disease in the back
