Mild Headache Causes

Headache is caused by irritation or injury to pain-sensing structures of the head. The structures that can sense pain include the scalp, the muscles of the neck and head, major arteries and veins in the head, the sinuses, and the tissues that surround the brain.

Headache may occur when these structures suffer compression, spasm, tension, inflammation, or irritation. The brain has no nerve endings so the brain itself cannot "hurt."

Research into the mechanisms of various headache types continues, and new theories arise frequently. Specifically, the causes of mild tension-type headache are not completely understood, and debate continues regarding the cause.

• A common theory involves nerve endings in the head that are irritated by tight muscles in the neck, face, and scalp, along with irritation to the arteries and veins nearby.
  
  
• The events that trigger mild headache vary widely among people who get headaches. Each person seems to have his or her own pattern.
  
  
• Common headache triggers
  
  
  • Stress
    
    
  • Before, during, or after menstruation
    
    
  • Muscle tension in the back and neck
    
    
  • Exhaustion
    
    
  • Hunger
    
    
  • Medications (Many drugs designed to relieve pain can actually cause headache when the drug is stopped after a period of prolonged use.)
    
    
  • Alcohol and caffeine withdrawal
  
  
• Other causes of headache
  
  
  • Household hazards such as carbon monoxide poisoning: If the headaches are recurrent or worse each morning or if more than 1 person in the household experiences the same type of headache, there may be an excessive level of carbon monoxide in the air. Carbon monoxide poisoning comes from faulty heaters or stoves that do not have proper exhaust to the outside of the house. If you suspect carbon monoxide poisoning, leave the building immediately and do not return until the levels of carbon monoxide are checked.
    
    
  • Headache associated with eye pain and vomiting: These headaches often indicate an eye disease called glaucoma and warrant immediate medical attention, or vision can be permanently harmed.
    
    
  • Headache that occurs with neck stiffness or pain, light sensitivity, fever, and confusion: These types of headaches could mean meningitis. This is a true medical emergency and needs immediate attention.
