A 21-year-old woman presents to the student
health center with complaints of a throbbing pain
on the left side of her head, nausea and vomiting,
and extreme sensitivity to light, noise, and head
movement. She also tells you she had a similar
headache 3 months ago that lasted for 2 days, and
she thinks she is developing migraine headaches
like her mother. She is concerned because she has
been unable to attend classes and has exams next
week.
A.
Are this woman’s history and symptoms
consistent with migraine headaches? Explain.
B.
Use the distribution of the trigeminal nerve
and the concept of neurogenic inflammation to
explain this woman’s symptoms.
5.
A 48-year-old man presents with complaints of
severe pain in his right foot after a crush injury.
He reports that although he had his ankle pinned
surgically, it still causes severe pain now, almost 1
year after injury. He states that he cannot stand to
have the sheets touch his foot, and even wearing
shoes is painful. His physician has diagnosed
chronic regional pain syndrome type I.
A.
Differentiate chronic regional pain syndrome
type I from type II.
B.
Explain the proposed theories of why this pain
syndrome develops.
