Pain weeks after epidural?

Has anyone else experienced this. I’m 5 weeks pp , I had an epidural that worked great lol. For about 2 weeks I had sharp back pain to where it hurt to stand. That went away but then it started getting sharp pain through my leg and whole leg going numb for a few minutes. Then it started in my big toe in the same leg . It’s only one leg this is happening. But the sharpest stabbing pain in my big toe all the time
