I never heard of these types of devices: it sounds like a gimmick, but it actually works. Overall, it's so light that I forgot that I was wearing it and didn't take it off until I was changing clothes an hour later. It fits under your clothes and discretely works its magic.

You're probably wondering…
What does it feel like to use Levina? +
You may experience intermittent or continuous tingling or pulsating sensations. Adjust the intensity to the highest comfortable level without causing pain for the most effective relief.
How does Levina relieve menstrual pain? +
Levina uses the gate control theory of nerves by sending special High-Frequency TENS modulation signals to the central nervous system through the electrical stimulator, keeping the sensory nerves "busy." This can disrupt or inhibit the transmission of pain signals to the brain, reducing or eliminating pain. Additionally, electrical stimulation can trigger the release of endorphins, the body's natural painkillers, further alleviating pain. Levina effectively relieves lower abdominal and lower back pain caused by menstruation. Place the electrode pads on the painful area for optimal relief—'where it hurts.'
How long does it take for Levina to relieve menstrual pain? +
You can feel relief within about 30 to 60 seconds after starting the treatment.
Will Levina affect my fertility? +
No—Levina is an external transcutaneous electrical nerve stimulation (TENS) device that does not interfere with menstrual cycles, hormonal balance, or other bodily functions. TENS only stimulates sensory nerves located beneath the skin. There is no evidence to suggest that TENS affects egg quality or has a negative impact on reproductive health. However, if you have any concerns about its effects on reproductive health, we always recommend consulting a doctor or medical professional before use.
Can I use it if I have a copper IUD installed? +
Yes—Levina can be used with a copper IUD. However, if you have concerns, we recommend consulting a doctor or medical professional before use.
Is this helpful for people with endometriosis, polycystic ovary syndrome (PCOS), or fibroids? +
Endometriosis, PCOS, and fibroids differ from common menstrual pain (primary dysmenorrhea). For those diagnosed with these conditions, we recommend consulting a doctor or medical professional before use.
