What is the principle symptom of atherosclerosis?
Pain

How is skin affected in arterial insufficiency vs. venous insufficiency?
- Arterial = cool and pale extremity
- Venous = red and warm extremity
How do ulcers occur in arterial vs. venous disease?
- Arterial = d/t trauma to toes/heel, painful, “punched out”
- Venous = stasis ulceration = painless in the ankle/medial malleolus areas, “cobblestone”
