Anyone have Arachnoiditis? When did it start and is it progressing? I have had 3 surgeries, 6 mri's with contrast dye and dozens of epidural injections. I read that all these contribute to this condition? How much time do I have before it becomes adhesive? I am getting drained seroma next week for a small pond of CSF. 4 Months post op L4-L5-S1 lami and fusion instrumented. My last MRI says lots of clumping in the area cauda equina.
