Prickly sure sounds like nerves to me. That is what I have thought when I get that. I wonder if a medication for nerve pain would help you. There is Gabapentin and Neurontin. Constipation can be combatted with stool softeners and magnesium. I am considering this myself.
I just finally left the house to run errands (first time to do that in weeks) and I could have just collapsed to the floor of the grocery store the pain is so bad. Right now I just want to cry but that will do no good. It feels like every muscle in there except my external sphincter is gone and it is doing all the work. I say external sphincter because this becomes even more pronounced after I use the ointment. I could feel it as a hard ball between my legs while I walked around and it felt like someone was pulling hard on my rectum (gravity?). I have had something like this following botox before but not THIS bad. Initially I thought putting more in the angry muscles I have now would help but I bet it would make it worse as this is how my body adapted to the last round. There needs to be some support back there. Weird thing is it feels a lot worse after I use the ointment (nifedipine) and I suspect this means that there is too much overall relaxation then. It could even be connective tissue that is hurting so bad. Wow! This is just mindblowing. Sorry to ramble....done now ;)
