Yeah, well, I'm not in a patient mood today, so I'll just say this is a load of idiotic horseshit not worth anyone's time or serious consideration, and leave it there.
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.
