Introduction

TENS (Transcutaneous Electrical Nerve Stimulation) therapy is a popular, drug-free method to relieve pain. Many people experience amazing initial results, but some notice that over time, the same settings feel less effective. This is a natural phenomenon known as tolerance.

Understanding how tolerance develops—and how to prevent it—can help you keep your TENS therapy effective for months or years.

What Is TENS Tolerance?

Tolerance happens when your nervous system adapts to repeated electrical stimulation. Essentially, your nerves get “used to” the sam

Introduction

When using a TENS machine, most people feel a tingling sensation, muscle twitching, or soothing relief. But have you ever wondered how TENS therapy actually interacts with your nerves? The answer lies in three key types of nerve fibers: Aβ, Aδ, and C fibers.

Understanding how TENS affects these fibers helps explain why it works so well for pain relief – and why choosing the right device, like the Totally TENS TPN Analogue Dual Channel Machine, makes a big difference in results.

TENS (Transcutaneous Electrical Nerve Stimulation) therapy is widely used for drug-free pain relief. But while many people benefit from it, some users notice uncomfortable skin reactions after removing the pads. These reactions can range from mild redness to more persistent irritation that discourages continued use.

If you’ve ever felt your skin sting, itch, or look inflamed after a TENS session, you’re not alone. Let’s take a closer look at the most common skin problems caused by TENS pads—and how you can avoid them.

One of the most common issues is temporary redness where the electrodes were placed. This usually happens

Choosing the right TENS (Transcutaneous Electrical Nerve Stimulation) pads is crucial for effective pain relief and comfort during therapy. Both hypoallergenic and standard TENS pads have their benefits, but understanding the differences can help you make the best choice for your skin type and pain management needs.

What Are Standard TENS Pads?

Standard TENS pads are the most common electrodes used with TENS devices. They are designed to provide effective electrical stimulation for pain relief and are compatible with most TENS units. These pads typically feature durable adhesive and gel that allows for strong conductivity and reliable performance.

If you use a TENS (Transcutaneous Electrical Nerve Stimulation) device for pain relief, you know how important the right pads are for both comfort and effectiveness. For people with sensitive skin, regular TENS pads can sometimes cause irritation, redness, or even allergic reactions. That’s where hypoallergenic TENS pads come in.

What Are Hypoallergenic TENS Pads?

Hypoallergenic TENS pads are specially designed electrodes that minimize the risk of skin irritation. Unlike standard TENS pads, they are made from materials that are gentle on sensitive skin, often latex-free and free from harsh adhesives or chemicals that can trigger allergic reactions.
