How do you identify the location of muscle-referred pain?

• A. Press on the muscle for 10 seconds and it will refer to the distant point.
• B. Massage the muscle until it hurts
• C. Measure muscle tension with a device
• D. Palpate the muscle and the pain stays local

Answer: (A)

Identifying muscle-referred pain comes from locating trigger points and using palpation to reproduce the pain pattern. When you press and hold a taut band in a jaw or neck muscle for about 10 seconds, a sensitive trigger point can activate nociceptors that send pain signals to a distant area served by the same neural pathways. If the patient reports the familiar pain in that distant location, you’ve mapped the referral pattern and confirmed a trigger-point source rather than just local muscle pain. If the pain stays local to the palpated spot, that suggests there isn’t a referral pattern from that muscle. Other approaches don’t reliably reveal this pattern: massaging until it hurts doesn’t consistently provoke the referred pain and can be misleading; measuring tension with a device doesn’t capture the referral phenomenon; and palpating with the expectation that pain remains local misses the key feature of trigger-point referred pain.
