Until the spinal marrow isn't damaged, she will recover and be
able to move normally. But the disc must be treated in a way which
doesn't hurt the spinal marrow. If the disc is pressing on the
spinal marrow, she needs a surgery to free this pressure, else she
could get paralysed.
It also can be possible that she will have to be careful with her
spinal chord for the rest of her life (careful with sports or
lifting heavy objects) and have pains caused by the disc from time
to time, but most probably she will return back to her normal
life.
