This itching is often accompanied with vaginal dryness. You may also experience burning around the vaginal wall, which might worsen with walking or physical activities. For some, this itchy, burning sensation can begin as early as 10 days before your period. For others, this may only occur for the duration of the period. This is completely normal and rarely a cause for concern. The symptoms can be relieved with basic preventive measures, such as proper tampon selection and ointments.

The Menstrual Itch. This is an itch that is again created by some type of imbalance within the body. I have noticed that about 2-3 days before my period arrives, my body, arms, legs, neck, etc itches constantly. It is like a background noise that is always there. If I dare to scratch any part then the eczema slowly rears its ugly head. Once the period starts, the itching subsides.
