So nice to see everyone again!

The neuro I saw last week has me scheduled for, among many other things, a somatosensory evoked response (SER) all 4 extremities -- he said he saw some sort of lesion on my MRI spine films that had not previously been picked up by others who reviewed the films and he wants to "explore this."

I've had EMGs/NCS -- bearable and sometimes downright unpleasant.

Any input on this test, and suggestions of what he might be looking for?

The reason for the test, as written on the form, says: "r/o myelitis" and "C-spine lesion."

Many thanks.

Little Mischief,
So good to see you again! Glad you found us. A lot of us are finding our way back. Here is a basic of the SER test. I'm not sure tho what your neuro is looking for. Maybe Glenn can help?

Thanks, Billye; yes, I can see that the community is coming together again.

That was a great link, the one I found was nowhere near as informative about the exam itself. I especially like the part about it doesn't hurt.

I think I did not do very well on the "tuning fork/vibration" part of his exam, and some of my reflexes were wonky.

Then of course there's the lesion -- I had been told my spine was "lesion free" -- I'll need to ask if this is new or truly something that was missed on a prior MRI done when I herniated a disk in 2000.

Best, Dottye

They measure how long it takes for a sensory impulse to make it up to the brain, and are generally not used to just make a diagnosis of pn, but to make a diagnosis of multiple sclerosis, or something wrong in the cord. neuropathies of large fiber sensory nerves can make this test abnormal. I think most people with sensory neuropathy will have normal SEPs.

I had them done, and I think they were looking to see if the nerve tracks which give information for balance were impaired. They were not. They are in B12 deficiency states.

So, my guess is they are looking for MS. Which is what you are concerned about, right?

Well, I have the dx of MS from two neuros going back to 1996, but this is a new doc and I have noticed that neuros tend to want to start from scratch when you walk in the door, regardless of prior diagnoses. A friend was undiagnosed with MS last week, and then diagnosed with Devic's syndrome. Not an improvement, just a change, one that she is refusing to accept.

However, he's the first one to mention a spinal lesion, if indeed that's what it is.

At the appointment, he seemed most interested in sxs of Sjogren's and/or connective tissue disease. I have tested negative before, 4 years ago, on SSA/SSB, he's retesting.

Also, PT/PTT, ESR , ANA, Anti-DNA ABs, extractable nuclear antigens I and II, ANCA, RPR, RA -- I should do this on Halloween, I see many vials of blood in my future.

I've been supplementing for some years now with Jarrow's Methyl B12 after testing quite low in the range, and when I'm occasionally re-tested I generally exceed the range. Since he has B12 on the lab form, I'll need to remember to tell him that I'm supplementing, and perhaps find the initial labwork for comparison.

I need to pull out your Lizajane.org spreadsheets and update them.

Thanks for the link, that's going to take some reading.

Best, Dottye

Dottye,
Remember Rose's instructions for B12 testing? You need to stop supplementing at least three days before testing and preferably ask for Rose's way of testing see:
