Oh no Rosiebottom! I'm so sorry I made you feel worse. That wasn't my intention.
I am sorry to say anything to make you feel bad, but I feel you deserve to get an honest opinion (others may disagree with what I say, so please take all this with the appropriate grain of salt). I feel I should warn you that, unfortunately, it's not uncommon for fissures to come back even after they are healed, especially if the problem is high sphincter tone and/or spasms. Having healed in the past does not always mean that you will heal with conservative measures again. In fact, it's just this kind of nasty behaviour of fissures that can make coping with them psychologically debilitating after a while - the good days, bad days, highs and lows that fissures can put us through for months and even years can be almost as bad as the pain itself after a while. Often, once the fissure is chronic (i.e., older than 6 weeks to one month), it is really hard to heal it with conservative treatments. Many boardies here struggled for years with fissures that would heal and then retear before they finally decided to have surgery - and going through that takes a real toll on one's psychological health. I'm sorry, hon. I really don't want to depress you. I just want to arm you with knowledge so that you can prepare yourself to beat this demon.
That said, it is certainly possible that you can heal this fissure with conservative treatments. It has been done. I completely understand that you wouldn't want to face another surgery after what you've been through (I've had gyn operations too, and they are not fun at all!). Most surgeons don't recommend surgery right away - they prefer that patients try conservative methods (like ointments) for a while before considering surgery. So you have time to work on healing with conservative measures. I do think, however, that when you are ready, you might reflect the possibility of a surgical option down the road. It may not come to that, but if it does, it's good to get psychologically prepared. This forum is a wonderful place for that. I was absolutely terrified when I first got here, but the people here really helped me deal with the pain, stress, and anxiety I was suffering, and this forum really helped me make the decision that was right for me. Surgery might not be right for you, but this is a great place to find that out.
Please don't feel too low. You are not alone. Many of us have gone through what you are going through and we understand how hard it is. We are here to support you, whatever you decide. Many of us arrived here very freaked out, but there are options and there is hope.
