Is It Normal to Experience Pain After COVID Vaccine During Pregnancy? - Obstetrics and Gynecology

Experiencing pain or discomfort after receiving a COVID-19 vaccine, especially during pregnancy, can be concerning for many individuals. It is important to understand that while some side effects are common, others may warrant further evaluation.
After receiving the COVID-19 vaccine, particularly the Moderna vaccine, it is not unusual to experience localized reactions at the injection site, such as swelling, redness, and tenderness. These symptoms typically arise as part of the body’s immune response to the vaccine, which is designed to help your body recognize and fight the virus if exposed in the future. The immune system's activation can lead to various side effects, including fatigue, headache, muscle pain, and joint pain, which are generally mild and resolve within a few days.

In your case, you mentioned experiencing swelling at the injection site and pain in the breast area (副乳). While localized swelling and pain at the injection site are common and usually resolve on their own, breast tenderness or pain is less frequently reported as a side effect of the vaccine. However, it is essential to note that hormonal changes during pregnancy can also lead to breast tenderness, which may be unrelated to the vaccine itself.
Given that you are in the early stages of pregnancy and have received the vaccine, it is crucial to monitor your symptoms closely. If the swelling at the injection site persists beyond a few days or if you experience severe pain, fever, or any other concerning symptoms, it would be advisable to consult a healthcare professional. They can provide a thorough evaluation to rule out any potential complications, such as an allergic reaction or infection.

It is also important to consider that the benefits of vaccination during pregnancy generally outweigh the risks. Vaccination can help protect both the mother and the baby from severe illness due to COVID-19. The Centers for Disease Control and Prevention (CDC) and other health organizations recommend COVID-19 vaccination for pregnant individuals, as it has been shown to be safe and effective.

In summary, while localized pain and swelling after vaccination can be normal, breast pain is less common and may require further evaluation. If you have any doubts or if your symptoms worsen, do not hesitate to reach out to your healthcare provider. It is always better to seek medical advice than to ignore potential symptoms, especially during pregnancy. Your health and the health of your baby are paramount, and healthcare providers are there to support you through this process.
