Answer 2

early dx
limb pain (burning, throbbing, aching and sensitivity to cold and touch)
local edema in extremity
changes in color and temp across one nerve root distrubtion
patchy bone demineralization on XR

Question 3

Question 5

Question 6

what happens to cause complex regional pain syndrome?

Answer 6

likely invovles reflex arc along sympathic nervous system leading to autonomic symptoms (sweating and abnormal hair growth, tissue swelling and coldness)

Question 7

how to diagnosis complex regional pain syndrome?

Answer 7

clinical diagnosis but can see abrupt symptom relief with regional anesthesia and local sympathetic nerve block and pts who have doubt w/ diagnosis may get autonomic testing (resting sweat output and skin temperature and axon reflex test) and bone scan (showing increased uptake or MRI-positive if showing thickened skin and edema and osteoporosis

Question 8

dysesthesia (painful itchy burning and restrictive dx) and weakness along anatomical areaof nerve root

Answer 8

cervical radiculopathy
