Severe Pain After Dental Surgery in Lyme Disease: A PTLDS Case
Can dental surgery trigger severe pain in Lyme disease? In some patients, the reaction can be far more intense than expected.
Quick Answer: In post-treatment Lyme disease syndrome (PTLDS), central sensitization can amplify pain responses, leading to widespread pain beyond the surgical site.
Clinical Insight: This pattern reflects changes in how the nervous system processes pain rather than the severity of the procedure itself.
A case reported by Lim and colleagues describes a woman with PTLDS who developed severe, full-body pain after routine dental extraction—requiring ICU admission.
For a broader overview, see Lyme disease symptoms.
Case Overview: Severe Pain After Routine Dental Extraction
A woman with PTLDS underwent extraction of four molars. Despite aggressive multimodal pain management, she developed severe, widespread pain after surgery.
Her oral pain was minimal—the primary issue was systemic pain requiring ICU-level care.
Baseline Condition: Severe Functional Impairment
Prior to surgery, the patient had been bedbound for approximately five years and required a wheelchair.
Her history included:
- Fibromyalgia
- Hypothyroidism
- Anxiety and depression
- Severe chronic pain
Her pain responded poorly to opioids but improved with ketamine—suggesting central sensitization rather than peripheral injury.
What Happened During and After Surgery
During the procedure, physicians used an aggressive multimodal regimen including fentanyl, ketamine, acetaminophen, and ketorolac.
Despite this, she developed severe, widespread pain postoperatively.
Additional medications—including opioids, benzodiazepines, and gabapentin—were ineffective.
A ketamine infusion was required, and she was transferred to the ICU for two days of intensive pain management.
Why Surgery Can Trigger Pain Flares in PTLDS
This response is explained by central sensitization—a state in which the brain and spinal cord become hyper-responsive to pain signals.
In PTLDS, the nervous system operates at an elevated baseline. Even minor stressors—such as surgery—can trigger disproportionate pain.
This mechanism is also seen in allodynia, where even light touch becomes painful.

Is PTLDS Truly Post-Infectious?
This case met criteria for PTLDS, defined as persistent symptoms following treatment for Lyme disease.
This raises an important question: are these symptoms truly post-infectious—or could they reflect ongoing infection?
Some clinicians attribute symptoms to central sensitization and immune dysregulation. Others consider the possibility of persistent infection.
This remains an area of ongoing debate.
Clinical Implications for Procedures
This case highlights the need for careful planning in patients with PTLDS.
Considerations include:
- Increased risk of severe pain flares
- Limited response to standard opioid therapy
- Potential benefit from NMDA-modulating treatments (e.g., ketamine)
- Need for multidisciplinary planning before procedures
Frequently Asked Questions
Can dental surgery trigger a Lyme disease flare?
Yes. In patients with PTLDS, physiologic stress can trigger severe, widespread pain.
Why didn’t opioids control her pain?
Because central sensitization affects central pain processing rather than peripheral tissue damage.
What is central sensitization?
A condition where the nervous system becomes hyper-responsive to pain signals.
The Bottom Line
Patients with PTLDS may experience severe pain flares after routine procedures.
Central sensitization can amplify pain responses, making standard pain protocols insufficient.
Pre-procedural planning should account for this heightened sensitivity.
