Dear Buggs:
Sorry that your having back pain. We usually think of radiating pain to be from a
nerveNerve biopsy
Nerve conduction velocity problem. Did you have an MRI of your back? Pain that does not radiate is usually not from the
dorsalParinaud syndrome roots or sensory nerves. Referred pain from colitis can give you a feeling of radiating pain, especially in your buttocks. It is difficult to tell you without having examined you and see you tell and show me where the pain is radiating from. Just judging from your age I would pursue the colitis problem first and then begin to address the possible back problem. However, a simple MRI of the spine might give you a quick and easy answer.
It is difficult to tell about colon cancer. The sigmoidoscopy will give you good information concernig CA.
Sincerely,
CCF Neuro MD
