Which statement best contrasts arterial and neuropathic ulcers regarding pain?

• A. Arterial ulcers have no pain; neuropathic ulcers have constant pain
• B. Neuropathic ulcers always have severe pain; arterial ulcers never hurt
• C. Both types always produce the same pain pattern
• D. Arterial ulcers have cramping or deep aching pain; neuropathic ulcers may have variable or absent pain

Answer: (D)

Pain patterns distinguish these ulcers. Arterial (ischemic) ulcers typically produce cramping or deep, aching pain that worsens with activity and improves with rest, reflecting reduced blood flow to the area. Neuropathic ulcers, seen with peripheral neuropathy such as in diabetes, often have little or no pain because sensation is diminished; when pain does occur, it is variable and not the same steady deep ache as in arterial disease. Therefore, the statement that arterial ulcers have cramping or deep aching pain and neuropathic ulcers may have variable or absent pain best captures the contrast. The other options misstate the relationship—for example, arterial ulcers do hurt, neuropathic ulcers are not always severely painful, and the two did not share the same pain pattern.
