Hi,
I have a condition which in early stages greatly resembles one posted by Annika here some years ago. I had surgery for removal of an arachnoid cyst compressing the right S3 nerve root at the S2 vertebral level. Weeks post-op, after an apparent full recovery of function, neurological symptoms once again appeared with this root, and quickly progressed to a worse situation than I had had pre-op.
Upon re-exploration to fix a suspected csf leak, the nerve was found tethered intradurally to scar tissue, and it is assumed my symptoms are a result of the adhesions and the pulling on the nerve root by ordinary activity. A similar experience occurred after the second surgery, and I am experiencing (among other things) numbness in the S3 dermatome (right), which has progressed quickly in the 7 months post-op from a third surgery, which found substantially more scar tissue than the first re-exploration adhering to multiple sacral nerve roots intradurally. The same recurrence of symptoms in the weeks and months post-op has occurred.
In situations where it may be assumed I have a post-surgical variant of adhesive arachnoiditis, is there any medication or treatment found to improve sensory nerve function, or otherwise arrest the slow loss of the same? The major impact of this is erectile dysfunction and perineal and penile numbness on the right side, and by sensory test has been found to correspond to the right S3 dermatome.
