Numbness and tingling in the arm where an infusion was given can sometimes happen, but it's worth paying attention to. It could be related to the IV site itself — sometimes the needle or positioning can irritate a nerve or the surrounding tissue temporarily.

However, since this is a new or unusual sensation, it's really important to contact your care team today and let them know what you're experiencing. Don't wait to see if it passes on its own. Here's what to keep in mind:

- New or worsening symptoms after an infusion should always be reported to your MS specialist promptly
- Numbness/tingling could be mild and temporary, but your medical team needs to assess it
- Don't hesitate — even if it seems minor, your care team would rather know sooner than later

With your lumbar puncture coming up next week, keeping your neurologist fully informed about everything you're feeling right now is especially important. They're your best resource here! 💙
