Any experienced fissure people out there? 
I was prescribed rectogesic for an anal fissure. I’m prone to them every time I’m stressed and have been since I was a child.
Tried it last night and Jesus wept, what a headache! Felt like my brain was pulsating. The box said to apply 2.5cm of the ointment but I only used about 1cm.
Does anyone know if I can build up from just a teeny smudge on the outside? Any way to prevent headaches?
It’s back to sudocrem I go for now!
