Soreness in the waist and buttocks during ovulation is a common physiological phenomenon that usually occurs between the 14th and 19th days of a woman's menstrual cycle. At this stage, the female reproductive organs begin to produce large amounts of mucus, which helps the fetus implant in the womb and also helps the woman eliminate waste from the body. However, for some women, uncomfortable symptoms may occur during ovulation, such as soreness in the back and buttocks.

Some people may think that the sour smell is caused by them sweating too much while exercising. However, this is not accurate. In fact, sourness may be a normal physiological reaction. When the female reproductive organs produce large amounts of mucus, it may stimulate the uterine muscles to contract, causing discomfort. In addition, the sour taste may also be related to women’s hormone levels. During ovulation, a woman's hormone levels change, which can lead to uncomfortable symptoms such as soreness in the back and buttocks.

While a sour taste may be a normal physiological reaction, for some women it can seriously impact their daily lives. Therefore, if women feel soreness in their backs and buttocks in daily life, they should seek medical help as soon as possible. Doctors can determine whether you have a viral or bacterial infection and develop an appropriate treatment plan by checking symptoms and conducting blood tests.

Soreness of waist and buttocks during ovulation is a common physiological phenomenon that usually does not have a serious impact on women's daily life. However, if the sourness is severe or is accompanied by other symptoms such as diarrhea, headache, nausea, etc., then women should seek medical help as soon as possible.
