if you are having new pain, you should let your doctor know about it.
since your prior steroid injections have helped at L5, it might help again for the left side at L2 possibly.
you should get a new MRI scan of the lumbar spine if you haven't had one recently.
when was your last MRI scan?
when was your last steroid injection at L5?
pain in the buttock area tends also to be L5 S1 dermatome.
so it could be the same L5 herniated disk on the left side causing your pain.
you might benefit from physical therapy
and also NSAID therapy like ibuprofen could potentially help as well.
if you are overweight, loosing weight can help decrease pressure on your spine.
it takes a lot of spinal nerve damage to cause loss of stool continence.
don't stress about this.
that is good.
you are welcome
let me know if you have questions.
if you can still feel when you have to have a bowel movement
you are not at risk for loosing stool control.
do you have other questions?
