My MRI states that I have 2 bulging disc at L3-4 and L5-S1 and moderate spinal stenosis at L4-5 narrowing the thecal sac to 8.7 mm. What does it mean?

In brief: Non-specific

24y female has reported unilateral sciatica 4 weeks post-delivery & MRI shows "spinal canal stenosis" L-4/5 & "disc bulges" lumbar regions.
MRI report does not explain symptoms; disc bulges oft seen in asymptomatic people. More likely birthing injured pelvic sacroiliac joint, now hyper mobile & impinging presacral plexus. Was excessive trendelenberg posture forced while had epidural anesthesia?

Largest joints in axial spine are sacroiliac joints, SIJ, & can be loosened by childbirth & injury. Lumbar nerves that conjoin as sciatic nerve lie on ventral sulcus of SIJ; pre-sacral plexus parasympathetics also. SIJ hypermobility can tug/stimulate these nerves, arousing back/pelvis pain, sciatica, IBS & Interstitial Cystitis.
Dr. Laurence Badgley
Pain of sciatica can be worse "resting than walking" because ground forces of chair seats and mattresses torque the pelvic girdle bony ring, impinging neural plexi contiguous to major pelvis joints, the sacroiliac joints. In women with benign Hypermobility Syndrome, SIJ subluxation becomes a consideration.
