💬In plain words
What the trial is, and whether it could suit you
The goal of this clinical trial is to test perineural injections (injections around a nerve) of incobotulinumtoxin-A in participants with diabetic nerve pain of the feet and lower legs.
The main questions it aims to answer are:
* Is the treatment safe and effective?
* Does the treatment affect participants quality of life, depression, physical activity, daily life, and sensation?
Participants will be treated every 12 weeks, for a total of 24 weeks, with either incobotulinumtoxin-A or a placebo.
