I am so sorry you are going through this. From personal experience, it's very, very upsetting to be faced with this. Something about what you are posting is putting up a red flag about your doctor.
1. Did you look at all of the lab reports? Did you notice if the margins were actually clear, for yourself? Why did your doctor have you come back in six months instead of three months after the LEEP?
2,. Did your doctor give you a thorough explanation of what you have, how extensive it is, where it's located, how many quadrants are involved, (Think of the cervix as divided into fourths.) if it's in the endocervical canal, and if there is any glandular involvement, especially in the endocervical glands? That would determine your treatment choices, right there.
3. Did your doctor thoroughly discuss the risks and benefits of all your treatment options - cryosurgery, laser, LEEP, or cold knife, before making a recommendation? In addition, since it hurt so badly when you had LEEP the first time, did your doctor mention giving you painkillers before the surgery or give you the option for having a sedative IV drop in office or general anesthesia in outpatient? There are risks involved with that, but a woman in that much pain could go into shock, which is another risk.
If you answer "no" to even one of those questions, please fire that doctor, immediately, and get a new one. Your life is too precious! It is your right to have a caring, ethical doctor who wants you to be as educated as possible so that you can make an informed decision. From what you have posted, I am questioning how much information your current doctor has actually given you. That you are posting your questions here puts up the red flag even higher.
Let me give you some links about cervical dysplasia and HPV.
This is older, but the info is very concise. If you go to the home page, it will also give a good overview of CIN.

Here is one of the few doctors I have encountered who still knows each case of dysplasia is different and each woman's body is different, so treatment has to be customized. He doesn't push the most inexpensive treatment option on women as the only choice.

This is an explanation about LEEP that also mentions the alternatives. I was impressed with the overall presentation of that clinic because they are thorough and fulfill the requirement by mentioning the other treatment options.

Here are some links about HPV.

Wikepedia is obviously not an expert's site, but it's a good starting point.

The good news is that there is medication in clinical trial, right now, that is proving successful. Nventa has HspE7, CNRS (Centre National de la Recherche Scientifique has MVA E2, and Roche has TG-4001, which is a therapeutic vaccine that targets HVP-16. The John Hopkins Medical Institute is also one of the few places doing research on therapeutic vaccines. We just have to contact our elected officials and push them to send funding to these biotech firms to get it available to women.

I don't know how people in other countries can reach their elected officials, so they would know better. But this is at least a starting point. There is hope!
In the meantime, I hope your PAP smear comes back normal. But make sure you get a copy of the lab report. And don't hesitate to fire your doctor if you aren't getting good answers.
