Pain and Leg Weakness - MRI or Myelogram?

I am female and 47. I have weakness in my left leg and have been progressively having more pain walking. I also have occasional pain in my left knee. An MRI reveals a pinched nerve at L2. My neurologist would like me to have a myelogram. I am deathly afraid of the epidural involved. 15 years ago in childbirth I had a bad reaction. My bp dropped dramatically and it did not take for pain relief. Should I have the myelogram or try PT again? I did it for six weeks last fall and got little relief. I am also considering VAX traction with a chiropractor.

Dr. Joshua’s Answer:

I won’t second guess your neurologist’s assessment of the situation. I’ll just say that in general, MRI is sufficient to determine lumbar spine stenosis and lumbar nerve root compression, which may result in leg weakness, pain when walking / radiating pain to the leg area. Myelogram is very rarely needed. If you are against having the myelogram, you could try and get a second opinion about the MRI and your symptoms, preferably from a neurosurgeon / spinal surgeon. Also, ask your neurologist why it is exactly he wants the myelogram done. I cannot say whether it should or should not be done in your case - your neurologist will be able to justify his recommendation.
