Period pain (menstrual pain) happens due to excessive contraction of uterus and it is frequently occurred to ladies in childbearing age. 
Medication such as painkillers or muscle relaxant are commonly used to alleviate such pain.
But these days, TENS (Transcutaneous Electrical Nerve Stimulator) is a new way of alleviating period pain.

HiCare Lady adds another neural stimulation to the path that the nerve transmits menstrual pain signal to brain. HiCare Lady disturbs the transmission of pain signals and consequently gets to relieve period pain.

Additionally, HiCare Lady itself can alleviate the pain while activating the secretion of hormone such as endorphins, which is effective in relaxing period pain.
