I have to disagree mildly with what** Stranger **is saying - some of it is absolutely correct, but if you are having numbness, then chances are higher than you’d think that there is an impingement of a nerve somewhere in spinal column. And bulges and/or stenosis don’t cure themselves, relatively speaking.
I did hundreds, maybe thousands of MRI’s/CT/myelograms and such in my days of X-ray/CT/MRI Tech on folks with similar symptoms and it was very common to find disc bulges/stenosis that were minimal and with bothersome sx’s but patient wanted to wait to see if things got better. It was very common to see same folk back in six months (or whenever) for a repeat ‘comparison-imaging’ to see if impingement had worsened or whatever. Usually, and I mean more often than not, things* were* worse, no doubt at all. I went through such a situation myself, and when both legs became gradually and totally numb (and I worked with for great Orthos and Neuros who told me to “just get the friggin’ surgery, dumbass!” many times) after walking a few yards or so a year or so later, I finally relented and threw in the towel and had my lumbar fusion/laminectomy. No probs since and was walking pretty much pain/numbness free less than 8 hours after operation happened! Had nurses worried but I felt free at last to move easily and Doc said if I could tolerate it, to just let me do what I could. Have to look really, really close to even see the scar on my lower back. My stubborness cost me a lot of quality-of-life time with my young daughter and teen sons, unfortunately.
Of course, having strong ‘core muscles’ and reducing possible obesity, etc, is always the best protection against (most) spinal issues, as Stranger said. Mine was purely foraminal stenosis (with rather slight disc bulging accenting my problem) where nerve(s) exit the spinal canal and radiate on downwards) of 95%+ narrowing bilaterally of the foramina! There was practically no room for nerves to exit the canal, so to speak. A very high degree of impingement. Neuro was totally shocked that I could even walk a straight line, to be honest, as he reviewed films with me and Radiologist I worked with.
Don’t be shy about getting some imaging done -> pics (ie Medical Imaging of appropriate modality, MRI in this case most likely, imho) are worth thousands of words and many, many opinions, IME of two decades of dealing with folks with sx’s as OP describes or close enough anyways. Getting a second opinion, if surgical fix is recommended, is not a bad idea either. And not long ago (5-10 yrs at most), most all Sports Orthos I worked with quit dealing with ‘spinal nerve issues’ - would refer to Neuro if there was any chance of nerve involvement. Just saying from my experiences, if that helps down the OP’s road.
And one last thing - success rates of properly diagnosed surgical procedures (and proper patient compliance post-op!) are not in general poor, trust me, as I was involved with many, many follow-up visits that had great outcomes. Folks with other non-treated sx’s/issues will gripe about a failed surgery when the particular surgery itself had nothing to do with those folk’s other issues. Folks with great outcomes don’t tend to preach to others about their great outcome, if that makes sense. Those with other probs will preach to whoever will listen about how bad their surgery was, IME.
However, for full disclosure, I was involved with two separate lumbar lami/fusion patients in one week where the two different ‘teams-of-two’ Orthos fused the wrong vertebrae-levels despite my near-perfect cross-table pre-op lateral lumbar X-ray w/ marker on patient’s back to allow counting the appropriate level to fix. Both patients were RN’s at hospital I worked with a lot, and I showed them their x-ray w/ Rad at my side to assure them it was not anybody’s fault but the surgeons for miscounting from where lead marker was placed for pre-op locating of vertebrae. That was last of any Orthos doing (most) spinal surgery at that hospital, fwiw. Neuros became the standard of care there for spinal ops and it seemed to be so at most other places I was familiar with. Not sure of applicability nationwide, but its the general approach in Idaho and Oklahoma, IME. HTH ya, **Mama Zappa
**Something that may help is to try and sleep with pillow(s) under knees (if you sleep on back) as this helps keep curvature of spine more 'natural/unstressed. May be worth a try is all I am saying. Hope all turns out relatively well for you - been there/done that, so to speak and I ignored it waaaaaaay too long despite it being something I knew about at a professional level. I was too focussed on working 60-70+ hours week at various places for money to restore a muscle car at the time and was money hungry. Kept telling myself I could hang in there til it was done - hindsight proves otherwise.
