Example
- Dysesthesia — pricking/tingling/pins-and-needles
- Yes
- Skin looks different — mottled/red
- Yes
- Exam: brush allodynia
- Yes
Result: LANSS 15 of 24 — neuropathic mechanisms likely (>= 12).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 12
- Neuropathic mechanisms unlikely.
- >= 12
- Pain of predominantly neuropathic origin likely (weighted symptom + exam items, 0-24). A screening tool, not a diagnosis.
