Neural Prolotherapy (NPT has a new name Lyftogt Perinural Injection Treatment) is a simple and very effective treatment for pain. It uses injection of dextrose (a natural sugar molecule) near cutaneous nerves that extinguishes neurogenic pain and neurogenic inflammation. Perineural injection therapy (also called neural prolotherapy or Lyftogt perineural injection therapy) helps calm pain and reduce neurogenic inflammation almost immediately.
