Do your lymph nodes swell during an MS flare?
Swollen lymph nodes aren't a direct symptom of MS flares. When you notice swollen lymph nodes during a flare, it's more likely caused by an infection rather than the MS activity itself.
Here's what might be happening:
* Infections like UTIs, colds, or flu can trigger pseudo-flares (symptoms that mimic a real flare)
* These same infections also cause lymph nodes to swell
* The timing might make it seem connected to your MS, but they're separate issues
A MyMSTeam member shared experiencing swollen lymph nodes after having a few colds, noticing them under the jawline and neck.
It's worth noting that some MS medications can increase your risk of infections by suppressing the immune system. This could make you more prone to infections that cause swollen lymph nodes, especially if you're on treatments like Ocrevus, Gilenya, Tysabri, or Lemtrada.
If your lymph nodes stay swollen for more than 2-4 weeks, keep getting bigger, feel very hard, or come with fever or other concerning symptoms, definitely check in with your doctor to rule out infection or other causes.
