Multiple Sclerosis Forum - possible MS symptoms ?

i am a 23 year old female. about a year 1/2 ago i had been exercising and a few hours later was sitting on my couch doing homework and all of a sudden my vision turned upside down, and the room started spinning. i went numb and tingly on left side of my body from head to toe basically. then i got a massive headache and became very very tired, and fell asleep for about 5 hours. when i awoke things were still very dizzy, and i felt naseauted. the lasting effect was weakness and tiredness for many months until about 3 months later the same thing happened, only my arms and legs were so weak i felt like i could not move. i did not see a doctor during this whole time period because i have never really had any health problems, and so i just passed it off as stress. the lasting effect from that "attack" i guess you could call it was sleep paralysis and hallucinations for many nights in a row (which after a sleep study surprisingly RULED OUT narcolepsy). so i went on again for many months until one day walking around at the zoo i all of a sudden became extremely weak and my knees started to buckle and i thought i was going to faint. the lasting effects from all of these attacks was just very tired and weak, and i started tripping and running into things. i also noticed that i felt fumbly and clutsy, which is odd for me because i have always been physically fit and was even on a dance squad for years. then i started having mild fevers with these attacks. most doctors attributed it to stress or mental illness and gave me anti-depressants because most labs were normal, which still did not prevent the attacks. i ended up being diagnosed with POTS (postural orthostatic tachycardia syndrome... which is an orthostatic intolerance) by tilt table testing. however the pots only is noticable to me during these attacks. in the past 3 months it seems like every few weeks or so some new symptom pops up that sticks around for about a week and then disappears. it started with difficulty swallowing, which lasted about a week after i exercised one night. then i started getting tingling and numbness in my trunk, arms, and feet, blurry vision (so bad could hardly read a book) sharp headaches that only lasted a couple seconds but would come multiple times a day for weeks, shooting forearm and jaw pains, constant nasuea, ear ringing for about a week straight, tons of muscle twitches (mostly in legs, hands, toes, trunk and eyes), sore legs and arms that feel as if they weigh 200 tons, and now most recently difficulty getting urine to pass (which i thought was a UTI, but U/A was normal), and everytime i touch the left side of my face it starts to tingle for about 5 minutes. i cant even lay on that side of my face because of the constant tingle. whats weird about all of these things is that although many are combined together during these attacks, they only last between a couple days to 2 weeks, and once they are gone i am fine. it seems like every system or part of my body has been affected at one point or another. also during these attacks i get very disoriented and confused and cant seem to think straight. i did have a tick bite about 2 years ago, so i asked for a lymes test but it was negative. the only neurological tests i have had are the tilt table and a MRI of the brain. tilt table showed OI, MRI of brain was normal. the only medications i take are allegra for allergies and prevacid for acid reflux. i also had a endoscopy and colonoscopy for the nasuea and it showed gastritis with hyperemic conjestion? i would really like an opinion. thanks.
