Specific causes of pain are too numerous to list. However, they can be broken down into various categories including:

• Injury -(mechanical- accidents such as falls, sprains, cuts)
  • (temperature-heat, cold)
  • (electrical-burn)
  • (chemical-acid burn)
• Disease- (cancer, kidney disease, blood vessel disease, heart disease, arthritis)
• Infection (viral, bacterial, fungal)
• Inflammation (brought on by disease, injury, infection)
• Oxygen starvation (brought on by disease or injury)
• Nerve damage (brought on by disease or injury)
• Stress (results in headaches, increased perception of pain and prolongs pain)
• Fatigue (increases the perception of pain and lowers tolerance to it)
