I have annular bulge at l2-l3 and l4-l5 which flattens the thecal sac. would this cause tingly feet bilaterally? what are treatment options?

Yes: Flattening of the thecal sac indicates you have central cord compression at both of those levels. This will cause bilateral numbness and potentially weakness of your thighs (l2/3) and knee/ankle (l4/5). Numbness is a warning sign of nerve compression. Some disc disease is amenable to therapy, injections, core strengthening but if symptoms progress or persist i would advise further eval.
