Pain symptoms in the front of the leg are more suggestive of a higher level involvement (L3-4 or L4-5 roots).
Your posture to relieve pain “feeling like i need to roll my pelvis down to “open up” my lower back” flattens the lumbar spine (flexion) and could be indicative of a facet problem or a foraminal narrowing.
Call Slavina, my nurse and send images. I’ll review them.
