Do I have Multiple Sclerosis?

I found out from my doctor that I might have Arthritis and we did blood test and they all came back normal. But my mom doesnt believe the test are right so were going to Get a MRI in July. My massage thearpist who's been helping me told me to write all my symptoms down and I did and she told me I could have Multiple Sclerosis because I have alot of the symptoms. I want to know if Multiple Sclerosis and Arthrtis can get mix up. Do i got MS? I'm 14 turning 15.
here is all the symptoms:

-All my joints hurt (Hands,legs,elbows,ect)
-Vision goes blurring
-I feel like I'm unbalanced.
- I have trouble going up and down the stairs. I have a hard time holding coffee cups and at one point I cant even lift at all.
-I feel very tired and often at weird times can start to fall to asleep,even tho I've had plenty of rest and it like in the middle of the day and about fifteen minutes later I can be totally fine.
-I feel like pins&needles.
-Jaw hurting
-i sometime freeze at the spot.

Usually, a patient is diagnosed with multiple sclerosis between 20 and 50 years of age, but multiple sclerosis has been diagnosed in children and in the elderly. Multiple sclerosis is twice as likely to occur in Caucasians as in any other group. Women are twice as likely as men to be affected by multiple sclerosis earlier in life.

MS has a wide range of symptoms. Common symptoms: Visual disturbances may be the first symptoms of multiple sclerosis, but they usually subside. A patient may notice blurred vision, red-green distortion (color desaturation), or sudden monocular blindness (blindness in one eye). Muscle weakness with or without difficulties with coordination and balance may occur early. Muscle spasms, fatigue, numbness, and prickling pain are common symptoms. There may be a loss of sensation, speech impediment (typically a problem articulating words), tremors, or dizziness.

It may take months to confirm a diagnosis. Tests are done to look for MS and to rule out other possible causes. Some diagnostic tests used are:
Blood work - look for Vit B12 deficiency and Lyme disease markers
MRI scans with intravenous gadolinium - identify and date lesions (plaques) in the brain. Newer lesions show up brighter.
Evoked potentials - hearing, vision, and motor impulses are tested to see if they move normally or too slow.
Spinal tap (lumbar puncture) - cerebro-spinal fluid is tested to identify cells that suggest MS. Can also be used to differentiate from Lyme disease.

For a definite diagnosis of multiple sclerosis, at least two separate symptomatic events or changes on MRI and a physical indicator (i.e. change in the central nervous system) must occur.

Hi Kagome,

You are very young to be dealing with such difficult health issues. The symptoms of a lot of diseases can overlap.
The previous answer was very good. I would suggest seeing a neurologist and an MS specialist if the MRI comes back looking like MS.
I hope that what you're going through is a minor thing and clears up soon.
I have an 85 year old Mother w/MS and i was diagnosed 25 years ago.

I have a Yahoo group on MS;

We have some members who haven't been diagnosed but MS could be a possibility. I wish you the best of luck.
