Great diagnostics Worrier. At least you are pinpointing more now where it is coming from. My guess would be that it is likely water leftover from your cleaning. You know, it's funny how opposite we are on this but I am so tight down there I would not be able to stick anything up there. Maybe the first 5-6mm is loose but after that it is tight and spasming and so sore
We are examples of two extremes I suppose. I am full of regret these days too. If I am healing it is so slow and then when and if I do finally heal I have the muscle aftermath to try to fix as I already had pelvic floor muscle problems before I got the fissure and every procedure has made it worse. Anyway...this is your thread, not mine ;)
I don't know if you know much about the internal sphincter and how it works but it constantly changes tone throughout the day depending on what is happening in the bowel, etc. In fact, anxiety has a pretty big effect on it. It can tighten it or loosen it and applying pressure can also loosen it. Maybe when you are looking and prodding it makes it looser for the time being and doesn't necessarily reflect how it is as you walk around throughout the day. I would really try to suspend what you think about your tone until you get your test results, as well as what your CRS says. Also, according to that article I posted for you, you haven't peaked in post-op tone yet so it could still improve. The tone in the part that was cut will never come back but the tone of the muscle that is left (and even if it was up to the dentate line there should still be 50% of your sphincter left) will get stronger.
For the time being I think you have to determine how to manage your symptoms. Maybe using a barrier cream would help with the soreness? I also have to wonder if maybe you are having pain that is from pelvic floor muscles as I have often thought that the skin burning feeling was due to that. Maybe you could see a pelvic floor physiotherapist while you are waiting to see your CRS? They are very insightful about the muscles down there and may be more help for you than a Doctor.
I know this was not what you had planned for your life Worrier. It is not for me either but I know if I sit and wallow in it I only feel worse. I also know it would likely end my marriage as my Husband just can't handle that anymore. Lately, my mantra has been for me to work on my patience and perseverance with this. It is a huge challenge for me as I am not a patient person but I am a very stubborn one ;) It is still early days and we both have lots of reasons to hope things are going to get better.
