Pain and backache during ovulation is a common physiological phenomenon that usually occurs during women's menstrual cycle. During this period, women's hormonal levels in the body change, which can cause a series of uncomfortable reactions in the body.

1. Changes in hormone levels in the body: When a woman’s eggs are released during the menstrual cycle, hormone levels in the body will change, causing soreness in the lower abdomen and waist.

2. Egg discharge: After the egg is discharged from the ovary, it enters the fallopian tube to wait for fertilization. During this process, soreness in the lower abdomen and waist may be a normal physiological reaction.

3. Stress: Sometimes, women experience stress during ovulation, which can lead to soreness in the lower abdomen and waist.

Although swelling, pain and backache during ovulation are a normal physiological phenomenon, if severe symptoms occur, such as pain that lasts for a long time and is accompanied by other symptoms, such as diarrhea, vomiting, fever, etc., it is recommended to seek medical treatment in time.

In addition, for patients with long-term chronic pain, it is recommended that while treating pain, pay attention to keeping the lower abdomen and waist warm and avoid excessive exercise or standing for a long time, which can help reduce pain.

To sum up, for the physiological phenomenon of swelling, pain and backache during ovulation, we need to maintain a relaxed attitude and seek medical treatment in time to obtain better treatment effects.
