TENS unit for period cramps

TENS stands for transcutaneous electrical nerve stimulation. Small pads deliver controlled pulses through the skin; many people describe the feeling as a comfortable buzz. The pulses can compete with pain messages reaching the brain and may support natural pain modulation. The unit does not thin the womb lining, change hormones, or diagnose the reason for cramps.

If period pain is intense, newly different, or associated with painful sex, unusual bleeding, bowel symptoms, or urinary symptoms, a healthcare professional can look for causes such as adenomyosis, endometriosis, ovarian endometrioma, pelvic inflammatory disease, or uterine fibroids.

Check the pads and cables before use, then attach pads to dry, unbroken skin on the lower abdomen or back as directed. Turn the intensity up gradually until there is a strong but comfortable tingling; it should not hurt or cause muscle distress. Keep the unit dry and remove it before sleep, bathing, swimming, or driving.

Do not place pads over the eyes, throat, or chest, or on numb, infected, or damaged skin. Get individual advice before use with an implanted electrical device, reduced sensation, epilepsy, or pregnancy. If the adhesive causes redness that persists, stop using it. Other options, including the Combined Pill or Hormonal Coil, may be suitable for some people.

Get urgent help for severe sudden pain, fainting, fever, heavy bleeding, persistent vomiting, or pelvic pain when pregnancy is possible. Book an appointment if cramps interfere with work or sleep, worsen over cycles, start outside menstruation, or return quickly after treatment. TENS should not delay assessment of a red-flag symptom.

Ask where to place pads for your pain, how long each session should last according to your device, and whether your medicines or medical conditions affect suitability. Ask what examination is appropriate if pain has changed.
