What could all these symptoms mean?

[summer808]

I am a 25 year old female and the symptoms I listed below have been occurring in the past 2-3 years. They're random and not sure if they relate to one another. What do you think it could be?

Sensation of quick side to side eye movement. I feel it however, because it comes and goes within seconds I have never been able to see if my actual eye itself moves or if it's just the sensation. There may be a day it happens twice or 3 times and I'll go months not experiencing it and then randomly happens again.
Urinary incontinence and some times feeling like I am exploding but very little is voided (I had a urine test done a month ago and came out clean no UTI)
Constipation
I had diminished sensation in my left forearm 6 months ago that lasted 2-3 days
I get random twitches and pains in my legs while resting
My thumb will twitch sometimes for a good 15-30 min
Once during a hangover I experienced one sided facial numbness that went away later
I am fatigued most of the time no matter how much rest I get
I get mood swings
Feel weak in muscles
I have mild-severe sensorineural hearing loss
Ringing in my ears that come and go

Only vitamin I am deficient in is Vit D and i tested negative for uti
Also i don't do any type of drugs

At age 25, I would contribute to vestibular disorders (dizziness, etc) before MS. Usually an ENT (otolaryngologist) treats that.

Acquired nystagmus (repetitive, involuntary, to and fro oscillation of the eyes) is most commonly caused by vestibular disorders, stroke, multiple sclerosis, trauma and drug toxicity.
