Okay, so far I havent gotten any answers. this is how it all began. in jan 2005, I noticed my left arm felt tired and kind of cramps up on me, but not painfully, then I was diagnosed with migraines by a neuro, had MRI etc. MRI was normal. began having dizziness and a pulsating in my right ear (which i get in my left sometimes now). saw ENT, had balance test which showed some weakness in both ears. so far thats gotten better, but i still get an off balance feeling. Then in summer of 2005, i began noticing the same tired/weak feeling in my left leg. can still use it the same, but gets tired and aches easily. Also began noticing that I get a lot of body twitching. Also started noticing that it seems like the lights flicker once in awhile. saw neuro again, said take a multi-vitamin. saw another neuro, looked at MRI and said everything looked fine. Since then, i have noticed a slight problem breathing as if my throat is closing up. Doctor said he can see spots in my throat likely due to an allergy or something. I dont have allergies. also, the weakness on my left side is bothering me, but comes and goes easily. Still see lights flicker. Wondering if I have MS or something. the doctor at health services at school mentioned it once. does this all seem connected? I'm 20 years old and my health is making me unable to focus on school or anything. I'm fine for a month or two, then I start noticing stuff again. or it is still there and I began worrying about it. does this sound like MS or anxiety???
