Expert:  Dr Anil Kumar replied 3 months ago.

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For a lumbar puncture, a sample of cerebrospinal fluid is withdrawn with a needle and sent to a laboratory for examination.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.

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?
Expert:  Dr Anil Kumar replied 3 months ago.

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.

Customer: replied 3 months ago.
I developed severe and apparently permanent adverse reactions as a result of Hepatitis B vaccine.
About 4 years ago I was completely healthy and very athletic before this vaccination and have now
suffered severe, debilitating autoimmune side effects from this vaccine. Such as getting joint pain,
and a limited range of motion when I lift weights in the gym, only on one side of the body, not in
both shoulders at once, just the left, previously I had no shoulder problems, I used to lift 100KG but
now I get joint pain when I lift 50KG and these started after vaccination. There's a measurable loss in
stamina before the vaccine to how I am now, I experience breathlessness much earlier when I do
cardiovascular exercise then before I had the vaccine. I have chronic fatigue and it is not improved by
getting rest. I have a dry persistent cough when there's nothing to bring up.I have a severe constant ache whenever I'm sitting down, it's on
the upper left side of my abdomen, next to my stomach and behind my left ribs, it's always in the same place.
This place hurts when I'm using my laptop or when I'm watching TV or when I'm sitting on the bus. Sometimes
I get sharp stabbing pain on the left side of my stomach. The ache seems to dissapear after I stand up. I
suffered the residual effects of all these symptoms for more than 4 years.What should I do (next)? Nerve Conduction Studies/EMG or Lumbar Puncture or something else?
Expert:  Dr Anil Kumar replied 3 months ago.

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.

Hope this helps.

Customer: replied 3 months ago.
Why would I need to see a Rheumatologist?
Expert:  Dr Anil Kumar replied 3 months ago.

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.

Hope this helps.

Customer: replied 3 months ago.
I haven't had any tests done for NCV and EMG though
Expert:  Dr Anil Kumar replied 3 months ago.

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.

Hope this helps.

What's the difference between Central Nervous System and Peripheral Nervous System?
Expert:  Dr Anil Kumar replied 3 months ago.

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.

Customer: replied 3 months ago.
NCS/EMG is PNS and Lumbar Puncture is CNS?
Expert:  Dr Anil Kumar replied 3 months ago.

Yes.

Customer: replied 3 months ago.
because my pain is on the upper left side of my abdomen, next to my stomach and behind my left ribs, is it a Central Nervous System problem or Peripheral Nervous System problem?
Expert:  Dr Anil Kumar replied 3 months ago.

It can be organ originated or PNS originated.

Customer: replied 3 months ago.
I showed my GP the area of the pain and he said it's the spleen. What's the difference between organ originated or PNS originated?
Expert:  Dr Anil Kumar replied 3 months ago.

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.

Hope this helps.

Customer: replied 3 months ago.
If it's organ originated pain, then will NCS/EMG or Lumbar Puncture pick it up on the test?
Expert:  Dr Anil Kumar replied 3 months ago.

Ultrasound/CT scan help in diagnose the cause of organ originated pain.

Customer: replied 3 months ago.
My doctor has arranged for a Ultrasound scan, if it is normal then does it mean it's not a organ related problem but a nerve or muscle related problem in which case I'd have to do NCS/EMG?
Expert:  Dr Anil Kumar replied 3 months ago.

Yes.

Customer: replied 3 months ago.
Which one is better an Ultrasound or CT scan for abdominal pain?
Expert:  Dr Anil Kumar replied 3 months ago.

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.

Customer: replied 3 months ago.
When would the CT scan be arranged, if Ultrasound is normal or if Ultrasound indicates a problem?
Expert:  Dr Anil Kumar replied 3 months ago.

In both of conditions,it depends on doctor's choice.

Customer: replied 3 months ago.
Isn't CT scans used for bony structures and Ultrasound for internal organs? Why would I need CT scan?
Expert:  Dr Anil Kumar replied 3 months ago.

No,It's CT abdomen.

Customer: replied 3 months ago.
What's the difference between CT abdomen and Ultrasound abdomen?

Expert:  Dr Anil Kumar replied 3 months ago.

Either Rheumatologist or Neurologist or both.

Customer: replied 3 months ago.
I have a severe constant pain whenever I'm sitting down, it's on the upper
left side of my abdomen, it's always in the same place. I showed the location of the pain to my GP and he said it's the spleen. This place hurts when I'm using my laptop or when
I'm watching TV orwhen I'm sitting on the bus. The pain is related to muscle movement and
positional. Sometimes I get sharp stabbing pain on the left side of
my stomach. The pain seems to dissapear after I stand up. I know it's not my stomach because when I eat, I can feel the food go down my system normally but then I sometimes get the upper left abdominal pain, it is different I can feel the stomach processing food and the upper left abdominal pain both at the same time, and they are in two different locations.1) Should I see a Neurologist or Gastroenterologists?
2) What tests would a Gastroentrologist do? I've had normal blood tests done and it all came out fine. I'm having an Ultrasound scan soon.
