Great question! The short answer is: it depends on whether it's a true relapse or a "pseudo-flare."

A pseudo-flare happens when an infection (or even a slight rise in body temperature) temporarily worsens MS symptoms — but it isn't a true relapse. In this case, yes, symptoms typically resolve within 24 hours once the infection is treated and the body returns to normal. A true MS relapse is different. It's caused by new inflammation in the central nervous system — not by infection. For a relapse to be considered genuine, symptoms must:

- Last more than 24 hours
- Occur at least 30 days after a previous flare-up
- Not be explained by infection or fever

So if an infection is triggering your symptoms, treating the infection should help. But if it's a true relapse, recovery depends on the inflammation itself calming down — sometimes with the help of steroids or other treatments your neurologist may recommend.

When in doubt, always reach out to your neurologist to help figure out which one you're dealing with. They can guide next steps and adjust your treatment plan if needed.
