TENS machine not working

[Sardee]

hey everyone!

I’ve been using a TENS machine for a while now, mainly on my lower back as it gets really painful. Today, it’s not working as well on my right side (which is worse for pain).

The machine isn’t broken, I’ve changed the batteries, new pads etc. I had it on level 20 and I could only feel a light buzz on my right side. But it still works fine on my left.

I’m just wondering if it’s linked to Endo pain/nerves? worrying that my nerves are getting worse round that area.

Thank you 🫶🏻
