Melody,

What I believe Glenn is saying (and I should let Glenn speak for himself) is that the MRI's of the lumbar spine do not cover the sacrum or coccyx. I am only adding this because I had to have 3 different MRI's done at once. He is right; they can't catch it all on one MRI. Xrays just won't show the soft tissue or rather nerve impingement. I would also ask for them with and without contrast.

And I sort of went through this very same thing Glenn is speaking of. It took my spinal PM and Urogyn to sort the whole mess out. But I thank God my own spinal PM was not one of those who thought, as Glenn states, that the sacrum is immoveable. And, then followed the nerve blocks and very specialized PT which is too graphic to go into here; suffice to say it worked!

Anyway, I believe Glenn is correct when he says this may or may not be Alan's problem. But again, I was basing what I said from reading your post about Alan's previous MRI and I tend to agree.

And one more thing. I really like my own Neurologist but she has been wrong on occasion. It is possible as Glenn states that I do have idiopathic small fiber PN. But it is very, very odd that every time I get facet injections in various areas, an RF or even a block of the ganglion impar my feet improve tremendously. So, again...just my thoughts since really, every test I have ever had excluding a punch biopsy showed nothing.
