The Claim
Repeated injury to masticatory muscles may lead to prolonged upregulation of nociceptive channels such as P2X3 and neuropeptides like CGRP in primary afferent neurons, which could prime these neurons for enhanced responsiveness and contribute to the development of chronic muscle pain.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you keep injuring your jaw muscles, it might make the pain-sensing nerves more sensitive over time, which could lead to long-lasting muscle pain.

What the research says
1 studyStudy: Repeated Muscle Injury as a Presumptive Trigger for Chronic Masticatory Muscle Pain
The study shows that when chewing muscles are injured more than once, they don’t heal well and cause nerve changes that make pain more likely, which supports the idea that repeated injuries can lead to long-term muscle pain.
