• Spontaneous - cough, sneeze, strain, athletic injury, result of rupture of arachnoid sleeve along a nerve root
45
What happens when moving towards an upright position

Tension Headache
123
About 1/3 of patients with persistent tension headaches had readily recognized
Sx of depression
124
Pathogenesis of Tension Headache
• Excessive contraction of craniocervical muscles and an associated constriction of the scalp arteries (?)
• Craniocervical muscles are quite relaxed by palpation with no evidence of persistent contraction by surface EMG
• Pericranial and trapezius muscles are hardened
• Nitric oxide creating central sensitization to sensory stimulation from cranial structures
• Inhibitor of nitric oxide relaxes muscle hardness and pain in patients with chronic tension headache
125
Treatment of Tension Headache
Analgesics - aspirin, acetaminophen, other NSAIDs
• Persistent or frequent tension headache respond best to cautious use of medications that relieve anxiety or depression
• Amitriptyline ODHS
