Are numb lips/gums that worsen throughout the day and tongue-biting related to MS?
Yes, many people with MS experience numbness in their lips, gums, and face, and accidentally biting their tongue is a common issue. Facial numbness affects between 2.9% and 13.6% of people with MS and may be one of the first symptoms.
The numbness you're experiencing could be related to MS lesions affecting the trigeminal nerve, which controls feeling in the face and helps with chewing and tongue movement. This nerve damage can cause unusual sensations in the lower jaw, teeth, and gums. Why the tongue-biting happens:
When MS affects the nerves controlling your mouth and face, several things can contribute to biting your tongue:
* Numbness - When your mouth and face feel numb, you're more likely to accidentally bite your tongue without realizing it, similar to after dental numbing
* Motor control issues - MS can affect the muscles in your mouth and tongue, making movements less precise
* Swelling - Once you've bitten your tongue, the swelling can lead to more painful bites in the same spot
A MyMSTeam member shared: "I keep biting my tongue in the same spot even though I'm trying not to." Managing these symptoms:
Try slowing down when eating or talking to reduce tongue-biting. If numbness persists after your MRI, discuss it with your neurologist - they can evaluate whether it's MS-related and recommend appropriate treatments. Some people find relief with corticosteroids during flares, though symptoms may linger for some.
Good luck with your MRI tomorrow!
