Perimenopause tingling and numbness are neurological symptoms driven by estrogen's role in maintaining the myelin sheath — the insulating coating around nerve fibres. When estrogen fluctuates, nerve signals misfire: pins and needles, burning skin, electric shocks. A 2025 study in the International Journal of Molecular Sciences confirms estradiol actively promotes myelin repair. Cathy explains the full mechanism and what evidence-based strategies actually reduce symptoms.

Migraines worsen during perimenopause for up to 75% of women — and 8–13% develop them for the first time with no prior history. The reason is specific: estrogen regulates CGRP, the primary pain-signalling molecule of the trigeminal nervous system. Stable estrogen suppresses it. Fluctuating estrogen allows it to surge — and the erratic hormonal swings of perimenopause produce the most frequent, most unpredictable attacks of any life stage.
