@jerid, Thanks for sharing your experience with the Low Level Laser Therapy (LLLT). You will notice that I changed the title of your discussion to hopefully bring in more members to benefit from your positive experience using the LLLT device to help with the pain from your chronic postherpetic neuralgia (PHN) caused by shingles. I also found some information that supports how it has helped you.

How often do you use the device to keep the pain in control?
