How much pain can anal fissures cause? i've had them for a while and it's becoming unbearable at times.

Can be very severe: Hi, Sorry to hear you are feeling so poorly. They can be extremely severe. I've had many patients before that told me it's like sitting on a firecracker, hot coal, red hot iron. I've also had patients where they can't even sit down or have periods where they are almost writhing in pain. Hope you can get treated for them soon! Hang in there
