Yes!! This description especially of the maddening tingling, buzzing pain and inability to pinpoint the location of the pain sounds exactly what I started dealing with in my early 20s (except on the right side). I had this on and off throughout my entire adult life. Long periods of standing or sitting still or working at a screen/computer definitely aggravated the problem for me. For me the resolution came one day in my mid to early 40's in a yoga class that I'd gone to not realizing it was a bit more challenging than I'd expected (it was a partial ashtanga series class) The instructor responded to my look of shock and horror that we were going to attempt full wheel (a back bend) by saying (correctly, as it turned out) "you can do a back bend". From that moment of fully opening my spine in that inverted direction, I have never experienced that particular, horrible creeping, tingling pain/numbness again. Sure, I've had pain and discomfort of various sorts over the ten or so year since Mark said " you can do a back bend", but I have never had that particular, chronic creeping tingling pain.
As a smallish counterpoint. I had chronic lower back pain for much of my 20s that increased until 29. I tried yoga around 27 and got pretty into it. I’m a flexible person so the back bends weren’t a problem, but after a few months I started to get a new thing: shooting, sharp pain that felt like a pinched nerve. It was definitely from the back bends, and once I stopped yoga it stopped.
Over the last two years I’ve “beaten” the back pain. I only ever get it on the rare occasions I pull super heavy work days and don’t stay mindful.
There was no magic bullet for me. You have to keep moving positions. I never work for more than 35 or so in the same position. Lean forward, mid, back, then take a break. Even lounging at intervals. Posture work is just a lot of small things and improvements at margin.
Hey, would you be open to contacting me at the email in my profile? I would like to very briefly interview you about your experience and try to learn from it.
