What does TENS actually feel like?
If you’ve never used a TENS device before, one of the most common questions we hear is:
“What does it actually feel like?”
And closely followed by:
“What’s the difference between high frequency and low frequency TENS?”
This post is about helping you understand what your body might experience, so you can approach TENS with confidence.
First things first: what is TENS?
TENS stands for Transcutaneous Electrical Nerve Stimulation. In simple terms, it uses gentle electrical signals delivered through adhesive pads on the skin to interact with your nervous system.
Those signals can be delivered in different frequencies via the parameters set inside.
They feel each feel different. Our parameters are evidence-based and are set up as follows:
Mode 1 (Green): High Frequency Continuous (Steady pattern)
Mode 2 (Blue): High Frequency Burst (A pattern that varies)
Mode 3 (Yellow): Low Frequency Continuous (Steady pattern)
Mode 4 (Pink): Low Frequency Burst (A pattern that varies)
Mode 5 (White) is a bladder calming mode
Modes 1-5 are selected by pressing the POWER button and intensities are increased by pressing the + button or decreased by pressing the - button. There are 20 intensities to select.
What high frequency TENS feels like
High frequency TENS is often described as:
- A light buzzing
- A tingling or humming sensation
- A feeling of surface-level stimulation
- Sometimes compared to fizzy soda bubbles on the skin
Most people find high frequency TENS:
- Comfortable
- Easy to tolerate
- Immediately noticeable
- Less intense
It tends to feel more external — like something happening on your body rather than deep inside it.
For many people, high frequency TENS feels calming, distracting, or grounding. It’s often the mode people reach for when pain feels sharp.
What low frequency TENS feels like
Low frequency TENS feels quite different.
People often describe it as:
- A slow pulsing or tapping (hence our name!)
- A deep, rhythmic base drum
- A sensation that feels like it’s moving into the body
- Sometimes described as “thuddy” or “rolling”
Low frequency TENS is usually:
- Slower
- More noticeable
- Deeper
- More body-wide in how it’s perceived
Some people love this feeling and find it deeply relieving. Others need time to get used to it. It’s normal to feel a little unsure the first few times, especially if you’re sensitive to internal sensations.
Low frequency TENS often feels more internal and immersive, rather than surface-level.
Which one is “better”?
Neither is better they’re just different tools. High frequency appears more in research articles and tends to be more recommended in the pelvic health field, however low frequency is also used in practice and anecdotally a great tool for many.
The most important thing to know is this:
👉 You get to decide what's right for you
Some people strongly prefer high frequency and rarely use low frequency. Others feel the opposite. Many people switch between the two depending on:
- where they are in their cycle
- how intense pain feels that day
- how overwhelmed or fatigued their body is
There is no “correct” response.
What TENS shouldn’t feel like
No matter the frequency, TENS should never feel like:
- sharp pain
- burning
- jolting
- panic-inducing discomfort
If it does, the intensity is too high or the pads need adjusting.
A good rule of thumb:
You should feel stimulated, not shocked. You can select your intensity level by pressing the + button until the sensation feels intense, then bring it back a notch or two by pressing the - button on your Tap 2.0
A gentle way to start (especially if you’re nervous)
If you’re new to TENS:
- Start on a low intensity (only press the + a few times initially)
- Begin with high frequency (Mode 1 or 2)
- Let your body get used to the sensation
- Build slowly
There’s no rush. TENS isn’t about pushing through — it’s about listening.
One last thing we want you to know
TENS is meant to be comfortable and give the feeing of instant relief.
When set up thoughtfully, it’s a way of working with your nervous system, not against it.
Your experience may change day to day — and that’s normal.
