Itchy skin, also known as pruritus, is an irritating and uncontrollable sensation that makes you want to scratch to relieve the feeling. The possible causes for itchiness range from internal illnesses, such as kidney or liver disease, to skin rashes, allergies, and dermatitis.
The menstrual cycle is not the same for every woman. On average, menstrual flow occurs every 28 days (with most women having cycles between 24 and 34 days), and lasts about 4-7 days. However, there is a wide variation in timing and duration that is still considered normal, especially if your periods began within the last few years. A small percentage of women have periods more often than every 21 days or less often than every 35 days. These variations may be normal. Often, if you are bleeding from the rectum or there is blood in your urine, you may think the blood is coming from the vagina.
The good news is that menstruation usually normalizes after about two years. Normal menstruation can last from one to eight days. For most women with regular menstrual cycles, their period will last for three to five days. That doesn't mean that anything is wrong if your period is longer or shorter. Period length can vary, and some lifestyle or medical changes may impact the duration or severity of bleeding and cramping.
