hey valentinak, I haven't posted here in a while (which I guess is usually a good sign in here). So for me I think I've finally overcame it. I had last inspection in the hospital last october and they told me the fissure was healed. However, I was still having strong pain in my butt going down my leg etc. So I told the doc this and she forwarded me to a physiotherapist as she said the pain must come from something else.
fast forward by 6 month. I saw that physio 10 times and in the end he gave up lowering my pain. I googled around about that pain and I kept getting "isciatic nerve" problems or "hamstring" problems for my kind of pain.
went to a Osteopath and he was actually able to lower my pain. At the same time I went to another hospital (rheumatology) to get it checked as the problem - apparently - lays in the back for this pain. so I had it checked out and doctor said it's no rheumatic problems whatsoever and it seems like it must be something with the muscles. so he forwarded me to a hospital internal physiotherapist. I've been there about 5 times now and the pain has almost vanished!!! I'm so happy now! It's still sometimes hurting a bit when I sit or do certain movements but it's at least 90% less than it used to be.
In terms of the fissure I think I have no problems anymore at all. BM is normal and no pain, also no burning pain afterwards. no bleeding. even after sex. so all good! I'm still very careful when I'm using the toilet. no unnecessary pushing and am careful when wiping my butt etc.
hopefully it will stay like that and not return anymore!
btw. I think the botox shot I got last fall was the key to getting my fissure healed.
