Itch w no rash

I have been experience itch all over my body with no rash and began with a pain in my head for almost a yr and half . And it comes more intense when I'm fertil. Please help

This is most probably related to your onset of menstrual cycle, and could be caused by an autoimmune disorder. Some women get migraines at the start of menstrual cycle. 

You ay want to see a doctor, but its a tough thing to resolve even for a doctor. 

Yeah I am documenting when start and I'm itching today as well and I check my circle and I'm a few days from ovulation so I'm fertil and I am 47. I'm not sure if this is the beginning of menopause or something serious . I had numerous blood work checking my liver, pancreas, kidneys and everything is ok .
