Hi ouch I have sent you a PM but Mr Brown is amazing he has years of experience and has the best bedside manner I have seen. He will listen to you and if asked may transfer you onto his NHS list
I'm not sure if you can have LIS with a seton in place but you should be able to have Botox which really did give me a good few months of pain relief.
I had spasms that literally floored me for hours sometimes up to 24 hours after a BM till they stopped. I ended up losing 8 stone as I was just too scared to eat. (I had a lot spare though)
I'm not sure if your feeding your baby yourself but if not ask your GP about gabapentin it really did work for me literally halving the pain, nothing else came close to touching my spasms.
I truly don't know how you are managing with a new born. You must be really strong.
Keep going because this does get better
