Percutaneous Electrical Nerve Stimulation (PENS)

Neurologist has suggested PENS and referred me to pain specialist. Has anyone had this? Or has anyone got any information about it?
I have a TENS machine and I understand the PENS has a similar approach but electrodes are put under the skin so the target area is more specific.

Is this the same as the ONSI??? If so Kala has had this done x

Sorry penny has just dropped - I was talking to Alotec a few weeks ago about this.........

....Preliminary data presented by Dr Nardi of Marcerata Hospital in Italy, at the 15th World Congress of Pain Clinicians in Granada, Spain last week, includes a patient with Cluster Headache who benefitted from 2.5mths complete relief after a single 25 minute treatment of PENS therapy®.

Algotec's unique PENS therapy® is a form of peripheral nerve stimulation. In the case of Cluster Headache, an electrically conductive Probe is placed along the course of a peripheral nerve to control pain.

PENS therapy® is an extremely safe, efficient and effective way to control a variety of neuropathic pain conditions..........

I would love to hear how you get on x
