Well, without reviewing the MRI of your lumbar spine, it is difficult to know if your issues are neurologic in nature.
Xrays do not diagnose herniated discs -- so that advice was correct.
It would be helpful to know what the actual MRI of the lumbar spine report showed in your case.
But certainly, having an appointment with a neurologist would be helpful in determining the cause of your pains, and to see if it is an issue with the lumbar spine, or perhaps another issue, such as fibromyalgia, or another myopathy or neuropathy.
My MRI showed nothing. As I stated, nothing shows up in any scan I've had so the Dr's never tell me anything is wrong. They act like it's in my head. I know I don't have fibromyalgia as I would be hurting all over, and I know others who have that. My pain is only in my back. I was told once I have narrowing of the canal in my back whatever the heck that means.
I know you can't diagnose, but your answer was hardly what I was looking for. What is the difference between myopathy and neuopathy?
Well - if you have narrowing of the spinal canal in your back -- that is called "lumbar stenosis".
This would be apparent on your MRI.
Which is why I think you should get the actual report of your MRI, instead of being told that your MRI showed "nothing".
Myopathy is an issue with the muscles, such as an inflammatory disorder that can cause muscular pain.
Neuropathy is an issue with the nerves, that can cause a "burning" type of pain.
I'm sorry, but you have to realize that it is very difficult for us to know what is going on, especially since your own doctors, who have seen your imaging scans and examined you have no idea. This would be best evaluated by a neurologist in person, who can actually review your MRI pictures.
