I'm a 64 yr. old femaie. I've had 7 lumbar spine surgeries. 5 of them were in 2002 due to a MRSA infection. As a precautionary measure all the instrumentaion was removed and I had a long Vancomycin I.V. treatment.
I had a CFS but was told it was repaired.

In 2006, I had a Revision surgery because the previous fusion didn't work.

2009, I went to UM due to severe pain and was told I had a CSF but as long as it was capped off, I didn't have to worry. I was also diagnosed with Arachnoiditis.

Now due to severe pain I had another MRI. Two findings I'm concerned about:
1. L1/2 a broad disk bulge with right paracentral disk protrusion and bilateral facet hypertrophy causing moderate to severe canal stenosis.
2. There is a midline posterior fluid collection from L2/3 - L5 measuring 7.4 x 2.3 x 1.4 cm suggesting a seroma or pseudomenmingocele.

Could these findings be the cause of my new severe pain in the right buttock and lower lumbar area. I had a Rhizotomy of my R. S.I. joint recently but that didn't help.

I have chronic pain in my legs, etc. , but that's manageable. I'm not able to walk very much with this new pain.

Can you help me understand and make any suggestions?
