Off balance, bad head pains, ear discomfort - do desperate - feel almost that my life has ended

Feeling so desperate - August 2010 - Feb 2011 felt poorly with 'off balance' feeling as if I was being pulled and pushed. High pitched sound in ears similar to the noise of an old television - pains in head rather than a headache - doc thought it was just depression but I pushed for MRI and a neurologist - scan was clear - neurologist couldn't find a solution. Bloods, urine showed nothing.

Felt somewhat better for about 8 months - now symptoms have returned with vengence and I feel so low and unhappy. In November this year I awoke in the middle of the night with what I can only describe as a 'knocking' noise in my ear (I think - or could be head??!) Since that event I have felt really poorly. Off balance all the time - pushing, pulling syndrome again - 'knocking' in ear or head have ceased but my left ear gives me pain sometimes (not deep in the ear but just inside the lobe itself) but my head pains worse - sometimes a stabbing pain - other times as if somebody is pulling my hair always on the left.

My doc just feels it is depression but I am depressed because I feel ill not the other way around. Pains killers do nothing. I have been to opticians and eye conditions are just as you would expect for a 55year old woman. Tried beta blockers for head but they make me feel worse. I feel my life has ended and I cannot attempt to live normally and enjoy my former joys of gardening and riding my bike.

Thanks eagar to help but still very worried. Indeed because of these everyday head pains and feeling off balance I went to another doctor who despite my MRI scan in 2010 and a neurologist visit were all clear he is going to send me for a Echo-Doppler of the supra-aortic vessels and another visit to a neurologist. I am scared out of my wits but maybe he was just being careful.
