First of all I want to say how pleased I am that you've had your lletz and that for you it has largely been a straightforward and reasonable trouble-free experience - that's really great and I am genuinely pleased that this has been your experience of this procedure. The fact that you are still waiting for your results after three weeks is (generally speaking) a good sign as well (typically you would have heard by now if there was any major problem or issue), so that is all brilliant news! :-)
Obviously I don't know you, but you sound like a sensible person and therefore I am sure you will understand that not everyone's experience is the same. This can be for a number of different reasons, ranging from the way in which it is carried out, the individualities of each person's anatomy and the nature of the problem that has taken them to that procedure in the first place. Just as with most other medical procedures, there is not one, uniform experience that everyone has. A lot of people have a reasonably straightforward experience, but some people don't, and a lot of people are somewhere in between. This is just because everyone is different, that's all. You're right that this forum is about advice, but more than that I think it about providing support. Sometimes women come onto this site and they are really very distressed, frightened and vulnerable. Whilst I completely understand that you may have felt unnecessarily anxious because you read things that in the end, did not turn out to apply to you, I think it's important to understand that these are not 'horror stories' but actually the experiences of women who are often feeling very vulnerable and alone. Just as it's important that you are able to come onto this site, ask questions and get support - and I'm really glad you've been able to do that - it's important that other women are able to as well, even if they are experiencing things in a different way to the way you have experienced them. Because after all, we are all different! :-)
I'm going to give you an example from me, because I think it might help: sometimes on this site I will see a post from someone who has had a recurrence of cervical cancer. Sometimes the symptoms that have resulted in the recurrence being diagnosed might be physical symptoms that I happen to be experiencing at the time. This will scare me because I will immediately think that maybe I am getting those symptoms because I've got a recurrence. Now, this can be scary for me, and so far the fact that I've been going through the same symtoms has not resulted in me finding out I've got cancer again, but the fact that I might find those posts challenging for me personally, and the fact that I might find them upsetting and worrying, does not mean that those women should not post those things. I do not believe that the intention behind posts on this site is to scare people, and actually I think it's really really important that women who are going through difficulties and often don't have anyone close to them who they feel they can talk to about what they're going through, feel able to come onto this forum and talk openly about what they're going through and how they are feeling about that. Everyone deserves support and understanding and after all, we are all responsible for our own feelings, so it is not up to the other women on this site to censor themselves on the offchance that it might worry me. My feelings are up to me, not anyone else.
I hope all that helps in some way. I'm glad you've found this site which, after all, is a great source of support for all sorts of women going through all kinds of gynaecological experiences.
