What happened: in June-July 2020, I started to get glute pain upon walking…it became more and more severe until even 2 miles was enough to bring it on. Weight lifting: it did not appear during workouts, though I grew to understand that certain exercise (heavy deadlifts, arching while bench pressing, arching while shoulder pressing) brought on the referred pain AFTER the fact…not during.
I also had foot tingles/leg tingles at night; sometimes extensive.
As you can see, I am quite bent forward when I walk; I think it was my body’s attempt to take pressure off.

I sought out PT for it in summer of 2021…fall of 2021..even walking from my car to a game was painful. I tried resting from all walking, this stretch, that stretch.
Well, I’ve had this spondylolisthesis for many years; it was first noticed in ..yes, 1978 (summer). I have a pars defect (fracture of the pars; aka spondylolysis) which lead to the L5 vertebra slipping forward, ahead of S1 (top of your tailbone). I’ve had episodes for some time, most lately in 2006, 2011, 2013, 2016 and this time, conservative treatment could not quite clear it up.
Update: I just looked at my records online; in addition to my spondylolisthesis (due to pars defect) I have lumbar spinal stenosis (due to the nerve root impingement) which causes neurogenic claudication. (heaviness and pain in the leg due to the nerve root being impinged
My S1 is tilted forward and the L5 slides down, even when standing straight (shear force).
This leads to a lack of space for my L5 nerve root, hence foot tingles, sometimes shin tingles, and glute pain on my left side at about .8-1.5 miles of walking (warmed up); .4-.6 miles of walking (no warm up).
PT has helped and strengthening my glutes and core has helped. But not enough.
So, after meeting with the non-surgery back doctor, he referred me to a surgeon.
The surgeon explained that the definitive treatment would be spinal fusion, but that while the operation would probably relieve the symptoms, it would probably lead to different problems down the road and start me on the road to more surgery.
So…epidural steroidal injections have a decent success rate and possibly stop the cycle of irritation.
I get mine a week from today.
