I'm great today thanks Rachael!
I applied a small amount (<1cm) of Nitro before this mornings BM and I've been pain free! Slight pressure before I applied the rest of the Nitro at 10am, but nothing sore.
I'll let you know what my CRS says about Botox but I think if my fissure doesn't heal I'm going to go down that route you know. My worry with LIS is that cutting the muscle may affect me when I'm a pensioner!
