singing problems and light head symptoms related?

Hi for over 2 frustrating years now my singing voice has been shot, my normal talking voice is ok, not raspy but i cannot hit a high note w/out my voice cracking rediculously.  And NOW since january i've had on and off light-headedness, as well as numbness in limbs.  The light-head has been fairly recent, but definitely the scariest, and actually got me to the ER this past sunday, that and arm numbness etc.  I can understand the arm numbness is most likely from anxiety, specially after dr testing and thinking nothing of it, but the light head is very freaky and definitely a 'new one' to me.  

I read somewhere else here that messed up sinuses could be the culprit and would make sense, as possibly would tonsils.  I've definitely had headaches lately, and some migraines.  My throats pretty much always dry, and i do seem to have nasal drip in my throat year round too.  I bought a humidifier but doesn't seem to help.  I also do remember having some weird light head episodes a few months ago, and I used my sinus rinse on them and it SEEMED to have helped, but who knows.

I definitely havn't had an MRI yet, THIS close to insisting on one just to rule out anything major brain-wise, and neck/spine as well.  All i know though is it SEEMS like if i do change my breathing, the light headedness DOES get better.  I know before i went to the ER a few days ago, i was just blowing my nose before it all started and i swear that i felt light-headedness from blowing my nose, i even said to my friend at the time 'jesus, i think i might have a sinus infection onTOP of everything else i might have wrong with me??'

BUT at the ER when i brought up the subject of sinus infection and inner-ear infection he basically just shook his head as if there was no way on either even though he didn't look up my nose or in my ear.  


SOOOOO, I don't know.  I am scheduled for a new round of blood tests, and going to do allergy testing as well.  I'm thinking a pinched nerve is POSSIBLE, neck maybe.  Low blood sugar/hypoglycemia is POSSIBLE too, but the longer things go both of those seem more unlikely.  My main problems that started 4 or so months ago were all stomach and G/I track, so nearly all our tests so far were specific for that area.  Barium, Sigmoid, Halter monitor for some skipped-beats, all seems 'normal.'  Now that i found this forum i definitely want to look into a sinus ct scan, and maybe MRI and maybe checking my tonsils.  I DO know that over the years the doctors always remark how large my tonsils are, and how 'someday' they should probably be removed.  

Umm IF i knew there was a doctor here i'd expect some professional feedback and advice, but we don't get that here, DO WE?  I could not find anything close to 'ear/nose/throat/dizzy' in the 'ask a doctor' section.

Either way, thanks for any helpful advice-suggestions in advance.

It just might be coming from the head and neck area.  Obviously, no one can say for sure.  Or it could just be cerebral allergies or inflammation in the brain caused by environmental or food allergies or food intolerances.  If your symptoms persist, especially the numbness, I would press your doctor for an MRI of the head and neck.

Good luck!
