pain after epidural ?

Ladies I need help !! My lO is now 8 months old, but I have had severe back pain after delivery. The first time I got the pain  was about 20days pp, but since then I have this weird but severe back pain !! Starts at the center of my spine, then travels to the lower back, then upper back, back to the center and then front, like my rib cages, and it gets so bad that sometimes I have hard time breathing. Could this be from the epidural ? I never had this in my life, this happened right after I had the LO
