Thank you for the reply.
The only comments made after MRI and CT were that there was swelling around the S1 nerve root, which the original surgeon thought maybe causing my symptoms. Apart from that there was no other comment made. The Nerve Conduction Studies were abnormal and indicative of S1 nerve root damage.
I guess all these weeks on with the same pattern of numbness and no improvement the Surgeon I sought for a second opinion believes that the damage to the nerve was probably caused during the dural tear. Having been told it is unlikely now to recover – i wondered if there was any way forward.
I really appreciate your response.
with thanks
