Why jaw muscles might hurt more when hurt again
Repeated Muscle Injury as a Presumptive Trigger for Chronic Masticatory Muscle Pain
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
When jaw muscles get injured more than once, they don’t get stronger like leg muscles do. Instead, they get more damaged and heal poorly, which might lead to long-lasting pain.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.
Systematic Reviews & Meta-Analyses
Max 100Randomized Controlled Trials

Evidence Score
Based on clinical experience or non-systematic literature reviews. The lowest level of evidence as they are most susceptible to bias and personal perspective.

Your muscles get used to tough workouts over time, so they hurt less and recover faster the more you do them.
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.
When you hurt a chewing muscle, your body might produce more of a protein called NGF, which could make the nerves in that muscle extra sensitive over time and lead to long-lasting pain.
Your jaw muscles don't heal as well after injury compared to leg muscles — they get scarred and don't fix themselves properly, at least in animal studies.
When jaw muscles get injured over and over, they don’t get tougher like arm or leg muscles do — instead, they get more damaged and weaker each time.
