Hi there
I had a harrington rod put in about 20 years ago. i've been having lower back pain and severe muscle weakness in my legs for a couple of months now. finally the neurosurgeon did a myelogram and CT scan. This found a blockage. they told me it could be a tumor or cyst. A doctor friend told me to get a second opinion, that it could be something else - related to my harrington rod. He said to try an orthopedic surgeon.

Has anyone experienced this? Of course i'm scared it's a tumor, but the fact that I have the rod makes me wonder if it is not a tumor and somehow something related to my rod.

Any help is GREATLY appreciated!!
