Answer
Dear Lori,

The "mass" means there is something "solid" in the front of the thecal sac which is the part of the spinal cord in the lower back.  This is causing your problems and pain.  The steroid can only covers up the pain and once the effect  wears off, the pain may be worse due to the activities you engaged in when you don't feel the pain.
