How can you know if you have cervical erosion?

Patient's question:

Patient Gender: Female
Age: 22
According to the advice of a doctor online, I underwent a routine vaginal examination to rule out the possibility of cervical erosion. Yesterday, I went to the hospital for the check-up and described the issues I had discussed online. The doctor only performed a test on my vaginal discharge. The results showed no trichomonas or Candida, with a cleanliness score of 2. She then prescribed Daktar cream and did not conduct any other tests. Additionally, I have no sexual experience.
How can I know if I have cervical erosion? What kind of tests should I undergo to determine if I have it? Thank you!

Doctor's answer:

Cervical erosion is actually a common manifestation of chronic cervical inflammation. Some patients think that cervical erosion really means tissue erosion and worry about it, but it's not the case. Due to the long-term non-healing of chronic inflammation, the original squamous epithelium on the surface of the cervix falls off and is covered by proliferated cervical columnar epithelium, appearing red and granular in appearance, which some people describe as "erosion."
Mild cervical erosion generally does not cause any discomfort, and the only symptom may be an increase in leukorrhea, which is easily overlooked. Moderate to severe cervical erosion is mainly characterized by an increased amount of vaginal discharge, requiring frequent changes of underwear or sanitary pads. Depending on the pathogen causing the infection, the extent and severity of the inflammation, the color, odor, and amount of discharge can vary. It can manifest as creamy mucus or pale yellow purulent fluid. Blood-stained leukorrhea or post-coital bleeding may occur if cervical polyps are present.
Based on your description, it is likely that you have cervical erosion. It is best to go to the hospital for a check-up.
