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.'

Research suggests adjusting the treatment intensity to the maximum tolerable level without feeling pain for the best pain relief. If the dosage is too low or the electrical sensation is too mild, you may not feel significant pain relief. Start with a lower intensity if your body is not yet accustomed to the stimulation, aiming for a tingling sensation while prioritizing comfort. As your body adjusts, gradually increase to the maximum tolerable intensity.

Absolutely! Research confirms that high-frequency HF TENS can alleviate various degrees of menstrual pain (lower abdominal or lower back pain due to menstruation). If you experience persistent lower abdominal pain, be sure to consult a healthcare professional.

You can feel relief within about 30 to 60 seconds after starting the treatment.

Levina is suitable for all females troubled by menstrual pain.

When used with care, the electrode pads can be used over 20 to 50 times. Replace them immediately when they lose stickiness or when the electrical sensation weakens. Ensure clean skin before use, and store the electrode pads in the ziplock bag after use to extend their lifespan.

Of course! Levina is designed to be lightweight and discreet. You can wear it on your lower abdomen or lower back under loose clothing for privacy. You might even forget you're wearing it!

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.

Every woman's menstrual pain is different. Some may need to use it for longer periods. If pain persists, you can use Levina continuously until relief is achieved! If you experience any discomfort, take a short break or reposition Levina to another area of the lower abdomen or lower back for relief.

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.

No, Levina comes with a built-in lithium battery that can be charged via USB, providing enough power for 12 to 15 complete treatment sessions when fully charged.

Yes. Levina effectively relieves menstrual pain, but research also shows that simultaneous use of high-frequency HF_TENS and painkillers is safe. Heat packs typically provide temporary relief, so it's recommended to use them before or after using Levina for enhanced relief (especially in winter).

Please refrain from using Levina if you: (1) Suspect or are confirmed to be pregnant (2) Suspect or have epilepsy (3) Suspect or have heart disease (4) Have a pacemaker or implanted device that may be affected. If unsure, it's advisable to discuss with your doctor before using Levina.

We recommend drinking warm water or tea to alleviate cramps. If the pain persists, it could be due to other physiological or health factors, and we suggest you schedule a consultation with a medical professional as soon as possible.

Levina use has no known side effects. The user manual outlines usage details comprehensively. TENS is a non-invasive physical therapy method that has undergone extensive safety testing and has been used by medical professionals for many years. It has received international certifications from the FDA in the United States, Canada, and Taiwan, guaranteeing its safety and effectiveness. The risk of any adverse effects is considered low, and TENS is generally regarded as safe and well-tolerated, with minimal side effects. Allergic reactions to electrode pads may cause mild skin irritation. We have used hypoallergenic hydrogel materials to reduce this occurrence. However, a very small number of individuals may still experience skin irritation or allergies. We recommend discontinuing device use and seeking medical advice if such a situation arises.

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.

Yes, Levina can be used with a copper IUD. However, if you have concerns, we recommend consulting a doctor or medical professional before use.

Some of our customers use Levina while sleeping, and it's generally safe. However, we don't recommend using it while sleeping to avoid accidental contact or startling, as you should always be aware of your body's response to the stimulation.

Levina is not indicated for relieving labor pain and should not be used during pregnancy.
