Dr. Qamar Khan answered:

I have 2 herniated disks and 5 buldges one of the hern's L2/3 is deforming the thecal sac, the report says lumbar spine straightening. what can i do?

Sciatica

Stringio
Pain in the distribution as you suggested describes the pattern of the nerve that travels in the leg called the sciatic nerve. The sciatic nerve is not the cause of the pain source, it is the result of an irritated nerve typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease requiring further evaluation by a spine specialist.

If .7 cm enhancing lesion in thecal sac near L4 is discovered on pelvic MRI, would you have Lumbar Spine MRI first and then go to Mayo, or would you wait and have Lumbar Spine MRI at Mayo?

Ask them

Magnetic_resonance_imaging
Whether you go to Mayo or another referral center (such problems are usually treated by neurosurgeons), each have there own preferences. Some like to review the study first, even before seeing you (so you could have the lumbar MRI, with and without contrast in your community). Others like the study done at their site so they can specify the MRI sequences they desire.
