Muscle Spasm Relief Map

Tap exactly where it hurts on an interactive body map and see which muscles usually send pain there (often a muscle that lives somewhere else, which is the part most guides skip). Then get precise pad placement for the Chirp Halo wireless muscle stim: which pads, where they go, which program to run, and what to pair the session with. Runs entirely in your browser.

Educational guidance based on standard TENS/EMS placement practice, not medical advice, and not affiliated with Chirp. Always follow your device's own manual, and read the safety notes before your first session.

Before you place a single pad

TENS and EMS are considered safe for most healthy adults, but electrical stimulation has hard rules. The map below already excludes the forbidden zones; this is the full picture.

Never place pads

  • On the front or sides of the neck (carotid sinus: can disturb heart rhythm and airway).
  • Across the chest or over the heart; never let current cross the torso from one pad to a pad on the other side.
  • On the head, face, temples, eyes, or mouth.
  • On broken, irritated, infected, or numb skin, or over varicose veins.
  • Directly over the spine's bony ridge: always sit pads on the muscle beside it.
  • While driving, operating machinery, sleeping, or in water.

Ask a clinician first

  • Pacemaker, defibrillator, or any implanted electronic or metal device.
  • Pregnancy: no stim on the abdomen, pelvis, or low back without explicit clearance.
  • Epilepsy or any seizure history.
  • Heart disease or arrhythmia.
  • Cancer, DVT / blood-clot history, or recent surgery in the area.
  • Diabetes with reduced skin sensation in the area you'd treat.

See a doctor instead

  • A spasm that follows a fall, crash, or other trauma.
  • Numbness, tingling, or weakness spreading down an arm or leg.
  • Back spasm with fever, or any change in bowel or bladder control: emergency care, immediately.
  • Calf spasm with one-sided swelling, warmth, or redness (possible clot: do not massage or stim it).
  • Spasms that keep recurring for more than a week, or pain that wakes you at night.
