These are the findings of an MRI lumber spine with and without IV contrast

Clumping of the nerve roots is seen extending from the upperL3 through sacral levels consistent with arachnoditis. A hyperintense T1 and hypointense T2 signal is seen incorporated within the nerve roots extending from the lower L4 through the upper S2 levels. this is not effected on the fat saturation sequence and most likely represents a hematoma. Schmoral nodes are noted involving the T11 through L1 vertebral body region.

In terms of pain and symptoms -what can we expect from these findings?
