Question
What should you do if your baby’s entire elbow swells after vaccination?
Answer
The swelling in the elbow that occurs after vaccination may be due to subcutaneous hemorrhage. This hemorrhage may appear as pinpoint-sized spots, known as petechiae, or it may form larger areas. Generally, no special treatment is needed if there are no compressive symptoms. For severe blood swellings, consider options such as aspiration or incision and drainage procedures.
