What happens with severe cervical erosion

Patient's question:

Patient Age: 23
Detailed Condition and Purpose of Consultation: There is some itching outside the vagina. After checking at the hospital, it was discovered that I have severe cervical erosion. Currently, I am undergoing physical therapy. I would like to ask the doctor if this condition is serious, and whether it will affect future fertility (as we haven’t planned to have children yet). I feel a bit painful during the treatment. Is there a better way to treat it? Thank you!
Current General Condition: I only went to the hospital yesterday. Yesterday, I had examinations and physical therapy done at the hospital. Currently, it’s still the same as before, with no difference.

Doctor's answer:

Hello: Don't have too much psychological pressure, as general treatment will not affect fertility. If adhesions occur, they can be treated with hydrotubation.
There are many treatment methods for cervical erosion, and appropriate choices can be made based on the severity of erosion. The main methods are as follows:
(1) Medication: For small erosion areas with shallow inflammation, the following medication methods can be used:
① 10–20% silver nitrate: Apply locally once a week, with 2–4 applications per course.
② Potassium permanganate: Apply locally after menstruation, and repeat the medication once after 1–2 months. When using the above medications, be careful to avoid burning the surrounding vaginal wall. Additionally, ensure sterilization during medication to prevent reinfection.
(2) Physical therapy: Used for larger erosion areas with deeper inflammation.
① Electrocautery: Use a specially designed electrocautery device to burn the erosion tissue, causing it to necrotize and fall off. The treatment should reach a certain depth for better results.
② Cryotherapy: Use a specially designed rapid freezing device to freeze, necrotize, and cause the diseased tissue of the cervical erosion to fall off. Liquid nitrogen is commonly used as the cryoprotectant, which can lower the temperature of the cryoprobe to -196°C. Apply it to the surface of the cervix to freeze and necrotize the erosion tissue, causing it to fall off and allow new epithelial tissue to regenerate. One session is usually sufficient for healing. Generally, there are no adverse reactions, though some patients may experience mild dizziness or lower abdominal pain.
③ Laser therapy: Most commonly uses a carbon dioxide laser treatment device. Apply the specially designed laser treatment head to irradiate the erosion tissue, causing it to carbonize, form a scab, and fall off, followed by the growth of new epithelial tissue.
