Nummular headache is a rare primary headache disorder characterized by focal and well-circumscribed pain fixed within a round-, oval-, or elliptical-shaped region of the head. The pain is usually mild to moderate in intensity but may be severe. Nummular headache is most common in women in the fourth to fifth decade of life. The temporal pattern may be chronic and continuous since onset, chronic evolved from episodic, or episodic. These headaches typically are unilateral, side-locked, and fixed in location, commonly affecting the parietal region. Many patients experience superimposed exacerbations of pain, lasting from seconds to days. Sensory phenomena, such as paresthesias, allodynia, and dysesthesias, are frequently reported in the region of the pain. Treatment with gabapentin, tricyclic antidepressants, or botulinum toxin may be helpful.
钱币状头痛是一种罕见的原发性头痛疾病，其特征为局限于头部圆形、椭圆形或椭圆形状区域内的、边界清晰的局部疼痛。疼痛强度通常为轻至中度，但也可能很严重。钱币状头痛在40至50岁的女性中最为常见。发作模式可能自起病就呈慢性且持续，也可能由发作性演变为慢性，或者是发作性的。这些头痛通常为单侧性、固定于一侧且位置固定，常见于顶叶区域。许多患者会经历疼痛叠加加剧，持续时间从数秒到数天不等。在疼痛区域经常会报告感觉异常现象，如感觉异常、痛觉过敏和感觉障碍。加巴喷丁、三环类抗抑郁药或肉毒杆菌毒素治疗可能会有帮助。
