Myelogram complications - leg, back, buttock pain

I had a CT Myelogram done in July, 2009 and during the injection of the dye, I felt severe pain in my lower back, legs, and buttocks.  The pain has not gone away and the doctors have been of little help.  The pain is an aching and burning pain that is in my lower back, buttocks and rear of legs.  It is very difficult to walk or sit.  The pain level is usually a 6 or 7 but can get to 9 or 10.  I have been on gabapentin since July but it does not help.  Does anyone have an ideas as I am getting desperate for help??  Thank you.

Hi,
Rare complications of myelography include injury to the nerve roots from the needle or from bleeding into the spaces around the spinal nerve roots. Inflammation of the delicate covering of the spinal cord, called arachnoiditis, or infections, can also occur. Your symptoms of pain may be due to one of these causes. Please consult a neurologist for the management of the symptoms. Hope this helps you. Take care and regards!
