Multiple sclerosis, usually shortened to MS, affects the brain and spinal cord. Damage to myelin, the protective covering around nerve fibres, can interrupt normal nerve signalling.
The facial pain most clearly associated with MS is secondary trigeminal neuralgia. However, people with MS may also experience central neuropathic pain, migraine, dental pain, jaw pain or another unrelated condition.
A known diagnosis of MS should not prevent ordinary medical and dental causes from being considered.
Assessment starts with the pain history rather than the MS diagnosis alone. A clinician may ask where the pain occurs, how long it lasts, whether it is triggered, whether pain continues between attacks and whether sensation has changed.
Care may involve a GP, dentist, neurologist, MS team, headache clinic, oral medicine service, pain clinic or neurosurgical team.
MRI may help identify a demyelinating lesion or another cause, but a scan does not replace clinical assessment and should not be interpreted in isolation.
Treatment depends on the diagnosis. TN, central neuropathic pain, migraine, TMD and dental disease require different approaches.
TN may be treated through the TN pathway. Other neuropathic pain may be treated with medicines used for nerve pain, taking account of MS medicines, other health conditions and possible interactions.
Specialist review may be needed when pain is severe, the diagnosis is uncertain, medicines are not tolerated or pain remains uncontrolled.
Facial pain can add to fatigue, uncertainty and cognitive load. It may affect eating, speech, sleep, work and independence.
A pain record can help distinguish brief attacks from persistent symptoms and show whether pain changes alongside other neurological symptoms.
Managing facial pain alongside MS fatigue, uncertainty and other symptoms can be exhausting.
Support for sleep, anxiety, low mood and coping can sit alongside medical treatment. It does not mean the pain is imagined.
If you feel unable to keep yourself safe, call 999 or go to A&E. For urgent mental-health help that is not an immediate emergency, use NHS 111 and select the mental-health option where available.
Yes. MS is a recognised cause of secondary TN, although most people with TN do not have MS.
No. Dental, jaw, headache and other neuropathic causes must also be considered.
It can, particularly with MS-related or central neuropathic pain, but a new bilateral pattern should be assessed.
Yes. MS does not rule out dental disease or TMD.
