Do you have sciatica? I have had it since 1991 but now that I am getting older (51 and perimenopausal), it seems like if I do something to aggravate the sciatica, the nerves in the bowel area get confused.
I often have the sensation of needing to go and find out it is just gas or the way I was sitting. I eventually go okay but have noticed that the odd sensations in the bowel area seem to be linked to pain in my back.
There is really nothing I can do for mine except just wait it out, go check when I get the urge to see if something really does come out, and every great now and then if I think it has gone too long without going, take an Ex-Lax.
