From what I’ve observed in 20 years of talking with chronic face pain patients, if you haven’t had a response to glycerol injection within six weeks, it’s not likely that this procedure will “kick in” at a later time. However, be advised that some patients report having had a successful Glycerol injection on the second time around, after a failure on the first.

This procedure is generally the least persistent of all ablation procedures, tending to last a few weeks to a year. Balloon compression may last up to two or three years, rarely beyond that point.
