This study is looking at ways to reduce the pain from onabotulinumtoxinA (Botox®) injections used for chronic migraine. Researchers want to see if putting a small piece of cotton soaked with 4% lidocaine (a numbing medicine) inside each nostril for 5 minutes before the injections helps more than cotton soaked in saline (salt water). The main goal is to measure how much pain you report from the injections. You may be able to join if you are 18 or older, meet the criteria for onabotulinumtoxinA for chronic migraine, and are scheduled for these injections at the study site. The current status of this study is unclear, and it plans to enroll 18 participants.

Study design

This is an interventional study comparing lidocaine to saline before onabotulinumtoxinA injections. It plans to enroll 18 participants.

What's involved

You would receive onabotulinumtoxinA injections after either lidocaine or saline is applied to your nostrils. Your pain will be measured immediately before and after the procedure, and again 12 weeks later.

Compensation

Not stated in the trial record.

Follow-up

Your pain will be assessed at the time of the procedure and again 12 weeks later.
