Does pain sensitivity change across the menstrual cycle?
Ischemic pain sensitivity (pain from blocked blood flow) increases after ovulation, but heat pain does not change with the cycle. The study was very small.
What they did
11 healthy women were tested at three menstrual cycle phases (after menstruation, during ovulation, and in the late cycle). Researchers measured pain responses to heat and to blocked blood flow, and measured hormone levels and tracked physical and emotional symptoms.
What they found
Women felt less pain from blocked blood flow in the early phase after menstruation, but more pain during ovulation and the late cycle. Heat pain did not vary across the cycle.
What it means for you
Ischemic pain sensitivity is higher after ovulation, possibly linked to hormone changes. This study is limited by a very small sample size of 11 women.
