Dont understand

I was in an automobile accident 16 mo ago. About 6 weeks ago Ihad an MRI, showed buldging at C5-C6. Doc ordered a myelogram. Myelogram showed disc herniation at C5-C6 with compression. But CT showed nothing, so what does it mean?

Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with a doctor.

Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.

Why did you have a MRI of your neck? Do you have pain or numbness in your arms/fingers? A herniated disc can be a source of pain in some people. It is important to know that in a majority of people, a herniated disc may resolve over 4-6 weeks. Pain usually eases within 1-2 weeks. Only a minority of people will ever need surgery. Thus, nonsurgical treatment options are highly encouraged. These include NSAIDs, hot/cold packs, stretching, physical therapy, muscle relaxants, etc. Indications for surgery include nerve damage resulting in muscle weakness, loss of bowel or bladder control, loss of sensation, particularly in the pelvis, and severe and progressive pain.

One means of assessing whether or not the nerve being pressed on by your herniated disc is impaired is a test called an EMG/NCS which assesses how fast the nerve conducts electricity and how the muscle responds. This type of test is done by neurologists in most centers. It would be best for you to discuss surgical and non-surgical options with your physician.

Lastly, it is not uncommon for a CT scan to appreciate a herniated disc as well as an MRI. CTs are great at looking at bone and examining for hemorrhage. An MRI is better for anatomy and other pathological states.

I recommend that you continue working with your physician regarding your cervical spine.

Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
