NOT MS: You have problems in the PERIPHERAL nerves. MS involves the CENTRAL nervous system, i.e., brain, spinal cord, and eyes. Your meralgia paresthetica had NO relationship to MS. ...Read more

Electromyography (Definition)

Emg (electromyography) is a test of your muscles and nerves. It is typically performed along with nerve conduction studies (ncs). The EMG portion involves placing a recording pin (like a fine wire antenna) into various muscles, looking for 'muscle distress signals' that could suggest nerve or muscle diseases/problems. Nerve conduction studies involve stimulating nerves ...Read more

Would MRI of brain and emg being normal rule out ALS or MS 33 yr old male.

Never say never: Yes, it is quite unlikely you have either ALS or MS, considering your test results. Hasn't the person who ordered these tests for you discussed this?

In medicine, few things are certain, but it is time to consider less serious causes of your symptoms. Muscle twitching is very common, and is often caused by benign conditions, such as exercise regimen changes. ...Read more

How can they determine if my foot drop is being caused by my Ms or Spinal Stenosis? I am having an EMG done in Sept. will this help tell which one?

How can they determine if my foot drop is being caused by my Ms or Spinal Stenosis? I am having an EMG done in Sept. will this help tell which one?

Quite simple: If you have spinal stenosis, your L-5 nerve root may well be compressed, but alternatively, you could even possess a peroneal nerve problem. An EMG can clarify totally, and if negative, the foot drop would be more likely due to spinal cord involvement in MS. If the latter, you should be treated for a relapse. ...Read more

If MRI doesn't show cause of foot drop (l5s1 protusion)and emg doesn't show nerve issue and you have back and sciatica pain, could MS be a possibility?

If MRI doesn't show cause of foot drop (l5s1 protusion)and emg doesn't show nerve issue and you have back and sciatica pain, could MS be a possibility?

Unlikely: Lumbar radiculopathy and peroneal neuropathy are much more likely, and sometimes the MRI findings are there but poorly understood. Further evaluation, emg/ncv of the lower extremities, and additional MRI eval for lateral recess l5s1. ...Read more

Normal brain/neck mri/emg.having tingle/numbness in various places over body along with muscke twitches.sound like MS or would MS be not all over?

Normal brain/neck mri/emg.having tingle/numbness in various places over body along with muscke twitches.sound like MS or would MS be not all over?

Tingling all over: It is highly unusual to have MS and a normal MRI of the brain and the spinal cord in the neck. Although MS can affect the entire body, MS is probably not the cause of your symptoms.

Muscle twitching, tingling and numbness can be symptoms of many things. How long do these symptoms last? Do they last for days, or minutes? Why do you have spinal cord compression as a diagnosis? ...Read more

I have MS and spinal stenosis. Emg shows l5-l4-s1 compression of nerve root. Orthopaedic surgeon won't do the surgery without neurologist ok.?

I have MS and spinal stenosis. Emg shows l5-l4-s1 compression of nerve root. Orthopaedic surgeon won't do the surgery without neurologist ok.?

Cautious : I would guess the surgeon is being cautious to make sure that the neurologist agrees that surgery will help the problem. Stenosis of the spinal canal is different than neuroforaminal stenosis. Emg is usually normal in canal stenosis and is sometimes helpful in neuroforaminal stenosis. Just because you have something wrong on EMG and MRI doesn't mean surgery is the answer. Ask twice, cut once. ...Read more

More info req'd: It sounds like you've had a complex Neurological work-up and are intereted in seeking a second opinion. I would be glad to help, yet would need to see more data before throwing a diagnostic assumption at you. Please gather your medical records (labs/imaging/etc) and schedule a virtual consult with me for further details. I'm interested and available. ...Read more

Clarification: You have multiple issues, and most would strongly implicate MS. But if an MRI of both brain and spinal cord is normal, you do NOT have MS. However, several other possibilities exist, and you need to clarify your diagnosis. May help to obtain another opinion. ...Read more

Can an anxiety disorder mimic symptoms like ms? Muscle twitches ,prickly sensation, numbness ?
Had normal brain,neck MRI and clean emg.

Effects of anxiety: Symptoms of prickling, numbness and twitching can occur in anyone, and they can be more noticeable to someone feeling anxiety.

Your tests are ok. That is great! Means those nerves are healthy. Maybe just oversensitive. ...Read more

Started as back pain then gradually all muscles pain with fibrillation MRI for L4 L5 MRI,MRA,mrv for brain CPK 69.emg&ncs cmap all nrml afraid of MS?

May not be MS: I would not normally think of pain as the first symptom of MS. If you have had a normal MRI of the brain, that would really be evidence against MS.

What about blood electrolytes, such as potassium and phosphorus? What about your strength? Is that normal? ...Read more

Symptoms, tests nl: (nl=normal)
It's tough to explain the cause of your symptoms, especially with a normal MRI of the brain, neuro exam and EMG. What about blood tests? What about other symptoms? There is probably a missing clue somewhere. It's not clearly in the neck.

Anxiety can cause this too, but that is hard to prove. ...Read more

ANXIETY LIKELY: Considering all your symptoms and negative exam and other tests like MRI,EMG and blood test.It is more likely to be due to anxiety.
But I see you are getting behavior therapy,and Cymbalta (duloxetine) which is used for Depression/generalized anxiety disorder
I will advice to continue to be followed up by your therapist and psychiatrist for your symptoms

Numb patches on one foot and muscle twitches including in the eye.Concerned about MS but had normal brain and neck MRI and clean emg.Anxiety?

Well now...: This being HealthTap and not a doctor's office, you won't get an answer to what it IS, but normal MRIs pretty much rule out MS and a normal EMG/NCS rules out a large-fiber neuropathy. Not everything our bodies do has a precise name or explanation. Sometimes you have to take the practical approach: If it goes on for 1-3 yr without change or anything else developing, it's probably benign. ...Read more

My neurological symptoms have stumped the doctors.....?

YOU HAVE:: A proven skin punch biopsy diagnosis of small fiber neuropathy, and you possess one of the many causes of such an entity. Could be pre-diabetes, but with the ANA issues, might look further into collagen vascular categories. Other considerations, include Celiac disease, Sjogren's, HIV, paraproteinemias, B-12, etc.
Would check anti-GM-1 with IgG, IgM, as you might have an autoimmune sensory neuropathy, and might respond to a course of IVIG. Can you visit a neuromuscular specialist? ...Read more

How to diagnose benign ms?

Benign MS: Benign MS occurs in about 15% of people with relapsing remitting MS. It means a person has 1-2 attacks of MS symptoms and no other symptoms the rest of their life.

Uncertainty: I am sorry you feel frustrated about getting a precise diagnosis. MS is a diagnosis that is made by coordinating the results of history, physical exam and imaging studies over time. Doctors may be reluctant to give your illness a label prematurely, and sometimes we just don't know. ...Read more

Variable: MRI images improve with higher magnetic flux, and a 3.0 T machine will show more lesions than a 1.5 T. But software is also critical, and such techniques as FLAIR, double inversion recovery, etc may find even elusive areas. If in doubt, might image both head and neck. ...Read more

What tests besides lumbar puncture can be used to diagnose ms?

MRI: An MRI of brain with and without contrast can be very diagnostic, but often MRI of neck added in ambiguous cases. The lumbar puncture certainly can be confirmatory, especially with elevated oligoclonal bands, but often is not necessary if other studies are convincing. We very rarely use evoked potentials these days, but might also assist in some cases. ...Read more

How do doctors diagnose multiple sclerosis (ms)? What are the typical symptoms?

Diagnosed by MRI.: Typically MS is diagnosed by mri, but in some patients may require a spinal tap or other specialized studies. These tests may include optical coherence tomography (oct) or visual evoked potentials (ver or veps). Symtoms include numbness and tingling usually on one side of the body starting in the hands and toes and progressing proximally. Weakness in the same distribution. Painful visual loss. ...Read more
