Hello and thanks for trusting me to help you. I am a board certified consultant with over 30 years of experience.
Electromyography and nerve conduction studies help to determine whether muscle weakness, sensory loss, or both.
Nerve conduction studies measure the speed at which motor or sensory nerves conduct impulses.
For a lumbar puncture, a sample of cerebrospinal fluid is withdrawn with a needle and sent to a laboratory for examination.
The cerebrospinal fluid is checked for evidence of infections, tumors, and bleeding in the brain and spinal cord.

Thanks for the follow-up.
Electromyography and nerve conduction studies is better test for neuropathic pain.
You should see a neurologist for further investigations.

Lumbar puncture might be suggested if there is any suspicion of infection,abnormal growth in spinal cord resulting in chronic nerve pain.
However chances are usually less in most of the cases.
Hope this helps.
I understand your concern.
And you should see a neurologist or Rheumatologist for a clinical examination to treat such symptoms.
They are more specialized in treating such chronic pain.
As you have debilitating autoimmune symptoms with normal NCV and EMG studies results so Rheumatologist is also specialized in treating such symptoms such as joints pain,limited range of motion,shoulder problems.
Sorry for confusion.
As per your previous reply-What would be the reason to do a Lumbar Puncture test if you had already done a NCS/EMG first and that showed you had no nerve or muscle conditions?
So I thought you had already done them.
If you didn't undergo such testing then you can firstly undergo NCV/EMG.
The central nervous system(CNS) contains the brain and the spinal cord.
The PNS(Peripheral nervous system) is everything else. So the nerves that run down your arms and legs. The ones that innervate your organs, contribute to metabolism, muscle contractions, and pain reception.
PNS contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. The PNS main job is to send information gathered by the body's sensory receptors to the CNS as quickly as possible. Once the CNS has understood the information, the PNS will relay the specific orders back out the body. The nerves that carry impulse to and are carrying information from the spine are called spinal nerves.
It can be organ originated or PNS originated.
Yes,possibly it's organ originated pain as the location you describe.
It's a complex to define the exact difference and all systems work together.
Ultrasound/CT scan help in diagnose the cause of organ originated pain.
Investigations are advised step by step.
first ultrasound and then CT scan.
As your doctor has arranged for ultrasound so you should go for it.
In both of conditions,it depends on doctor's choice.
No,It's CT abdomen.

Either Rheumatologist or Neurologist or both.
Usually just after ultrasound performed.
Possibly same day.
