Pain in the left side of the lower abdomen during ovulation is a common physiological phenomenon, also known as "egg pain". This phenomenon usually occurs within a few days of ovulation, as the egg begins to develop and prepare to implant. However, for some people, egg pain can become a source of discomfort or even pain.

The cause of egg pain can be due to a variety of factors, including:

1. Inflammation: Gentle massage or exercise on the left side of the lower belly may help relieve egg pain. If the pain is severe, it may be due to inflammation.

2. Infection: If you feel pain on the left side of your lower belly, it may be caused by an infection. In this case, your doctor may recommend medication or other treatments.

3. Stress: In some cases, stress may affect egg pain. In this case, try some relaxing activities like meditation or yoga.

Egg pain is a common physiological phenomenon that usually does not have much impact on physical health. But if your symptoms are severe, you may need to seek help from your doctor. Your doctor may perform some tests to determine the cause of your symptoms and may recommend medications or other treatments.
