Last 2 days I have had lots of pelvic and lower back pain after a bowel movement and now my bum is numb on the top left of my buttock and around the base of my spine. Shooting pains in vagina and rectum as well. I googled and read about something called cauda equina and now panicking a bit. I can still wee and poo ok, if slightly more urgently running to the loo than normal. Bowels a bit more loose than usual but I am due on my period and have ibs so... Could it be something else not so urgent as cauda equina? The pain eases up a bit after a while but is still there a bit and the numbness is still there all the time. I really don't want to go to A&E unnecessarily. Could it just be sciatica or something? I've had pelvic pain for a long while now but it's got significantly worse these past few days.
