You’ve mentioned the tingling in your bum. You must be very vigilant for red flag symptoms - either numbness between your legs, or lack of control of bowels/bladder (that includes not being able to go, or stop.) These constitute a clinical emergency - called cauda equina - and there’s only 24-48 hours to have surgery, or else it can become permanent.
I’ve had 4 spinal surgeries, including a spinal fusion the last time (because I developed cauda equina, and I’d already had three microdiscectomies, laminectomies, and nerve root decompression - and the nerve root blocker injections were by working any more). Surgeon says that there’s no way he’s doing any more, unless it’s ‘pretty catastrophic’.
I’ve been super vigilant with all of the exercises, Pilates daily, swimming 3 or 4 times a week, physio every week, for 7 years. I am someone who has a shitty back. Don’t sit, stand, or lie for too long. Set yourself a timer for every 30 mins if you can, and change position/walk around the room/have a wee stretch. Obviously, sleeping is ok!! But keep the muscles active.
So, this isn’t a tale of my woes, but a warning that you can do EVERYTHING right, and it still go wrong. But equally - it might go away in a few weeks! They reckon 8-12 weeks is the time for most herniations/bulges to resolve. So please please, if you get the cauda equina symptoms, take yourself straight to A&E, if you’ve not already got a neurosurgeon. (And all the medic friends/colleagues I worked with said don’t let an orthopaedic surgeon do it - insist on a neuro surgeon!)
Good Luck. It’s fucking grim, and utterly relentless pain. Get the doctor to prescribe you a decent nerve painkiller too. It can really help.
