Hi Missy,
My CRS doesnt think botox is a good procedure because of the very high reoccurence rate. I went with the LIS and the pain is actually less than fissure pain. Best decision of my life, you should highly consider it and speak to your doc if you can get a CRS. My doc recommended against soft serve type of stool because while it doesnt hurt as much as a bulky one, it doesnt stretch the internal sphincter and promote blood flow. You should look for a CRS and talk about LIS, it is the best treatment for it. I was afraid for YEARS then i finally bit the bullet and i wish i had done it sooner. I feel normal for the first time in 8 years, you should ask about the surgery.
As far as the stretching, some people have the adverse reaction of tightening up after botox instead of loosening, and the effect is only temporary, youll more than likely go back to your old ways down there. LIS seriously saved my quality of life, and i completely understand and feel your agony. Im 3 weeks out and I feel about 90%, no issues really just extra time to make sure im really clean down there after going to the bathroom. I hope this helps
