I'm not a doctor, but I can offer some general information. A swollen clitoris can be caused by various factors such as irritation, infection, or hormonal changes. It's important to follow your doctor's advice regarding the injection and medication prescribed. If you're still experiencing discomfort or have concerns, it's best to reach out to your healthcare provider for further evaluation and guidance specific to your situation. They will be able to provide you with the most accurate diagnosis and appropriate treatment options. Remember, it's always better to consult a medical professional for personalized advice rather than seeking help online.
