Rate pain right now, least and worst pain in the past 24 hours, plus activity interference (Brief Pain Inventory–style wording). Get average pain intensity, a combined index, and mild / moderate / severe bands for visit communication. Pair with our opioid MME calculator only in supervised teaching—not for self-prescribing. Not the full BPI.
Last updated: June 5, 2026
Does not diagnose, prescribe, or replace emergency evaluation. Red-flag symptoms need urgent care regardless of a low score.
0 = does not interfere; 10 = completely interferes (educational wording).

Moderate overall burden: useful language for visits (“my average pain is about X/10 and it interferes with activity Y/10”). Track changes over time rather than a single snapshot in isolation.
NRS anchors are subjective; use the same scale over time for trending. Opioid decisions require full assessment—see a dedicated MME tool only under clinician oversight.

Integer 0–10 scales with teaching bands for intensity, interference, and combined index.
| Score | Label | Clinical context |
|---|---|---|
| 0 | None | No pain reported |
| 1–3 | Mild | Noticeable but often manageable with OTC analgesia / activity modification |
| 4–6 | Moderate | Interferes with some activities; often prompts clinic visit |
| 7–10 | Severe | Dominates attention; urgent evaluation if new, sudden, or with red flags |
| Step | Formula | Example |
|---|---|---|
| Average pain intensity | (Now + Least + Worst) ÷ 3 | (4 + 2 + 6) ÷ 3 = 4.0 |
| Combined index | (Average pain + Interference) ÷ 2 | (4.0 + 5) ÷ 2 = 4.5 |
| Descriptor bands | 0 none; 1–3 mild; 4–6 moderate; 7–10 severe | 4.5 → moderate overall |
| Validation | Least ≤ Worst over 24 h | Least 6, Worst 4 → error until fixed |
| Item | This calculator | Full BPI |
|---|---|---|
| Pain right now | Yes — NRS 0–10 | Yes |
| Least / worst past 24 h | Yes — two anchors | Yes |
| General activity interference | Yes — single item | Yes (+ 6 more domains) |
| Sleep, mood, walking, relations | No | Yes — full BPI interference scale |
| Validated scoring certificate | No — educational | Yes — research/clinical license |
| Scale | Population | Method |
|---|---|---|
| NRS 0–10 (this page) | Adolescents & adults | Patient selects integer 0–10 |
| Visual analog (VAS) | Adults | Mark 100 mm line; converted to 0–10 |
| Wong-Baker FACES | Children ≥3 y, cognitive impairment | Choose face matching pain |
| FLACC | Infants, nonverbal | Observer scores Face, Legs, Activity, Cry, Consolability |
| Symptom | Action |
|---|---|
| Thunderclap headache | Emergency — subarachnoid hemorrhage concern |
| Chest pain with dyspnea | Emergency — cardiac / pulmonary evaluation |
| New focal weakness or numbness | Urgent — stroke, cord compression |
| Fever + severe back pain | Urgent — epidural abscess, osteomyelitis |
| Severe abdominal pain + rigidity | Emergency — surgical abdomen |
| Tip | Detail |
|---|---|
| Same time window | Always “past 24 hours” for least/worst—do not mix 12 h and 24 h entries |
| Log medication timing | Note if “least” followed analgesia—helps clinicians interpret averages |
| Trend ≥3 data points | Single snapshot less useful than before/after PT or dose change |
| Bring interference | Intensity 4/10 with interference 8/10 tells a different story than intensity alone |
Wide least–worst spread (1–8) captures day-to-night variation after surgery—averaging prevents over-relying on a single “right now” snapshot.
Educational use only. This calculator does not output licensed Brief Pain Inventory scores, prescribe analgesics, or triage emergencies. Call emergency services for chest pain, stroke symptoms, or sudden severe pain.
