Light headed/dizzy, shaking, weak, numb/tingling on fingers and toes, flushed

[Med Q]

Two weeks ago around 6pm I had an episode of multiple symptoms that precipitated very quickly, within about three minutes, without warning.  These included feeling very weak, shaking all over, light headed/dizzy,numbness/tingling on fingertips and toes, slight shortness of breath and chill.  I felt like passing out, flushed.  I figured it was from not eating so I grabbed a burger and it seemed to alleviate the problems.  Well, it happened again around the same time of day a few days later. But this time, eating didn't help as much.  Eventually the symptoms went away.  My colleagues observed that I looked very pale.  Since then, I have been experiencing episodes every day in the evening.  I keep a pile of energy bars in the office and gulp one down at the very first hint of weakness, shaking, which seems to go away in about ten minutes.  If I don't, the symptoms quickly intensify until I am so shaky and weak that I can't remain in a sitting position.
I've had blood/urine test and was told all is ok.  
Here's the curious part.   Last two days, instead of gulping down an energy bar, I've been taking Vitamin B-12 that dissolves under the tongue.  This seems to help alleviate the symptoms as well as the energy bar.
Any thoughts or guesses on this will be gratefully appreciated.
Thank you

My goodness  sounds horrific,I have  done the same thing thank God my 19 yrs old son was home,I tolled him right when I felt awful , It was like, you know  something  is about to happen  seriously  scary,I said"call ambulance " !

Reading all these comments i'm glad that i'm not the only one who's going thru this. It literally feel like i'm going mad and i'm almost giving up on life. Especially when the doctors say ur fine and u know ur not and all the tests come back negative, not that i want any of them positive, but i hope u understand. it feels like hell when u dont know whats wrong with you. I've had some of these symptoms for 5 moths now. It all started when i visited a doctor for a H Pylori infection. Before that i had had a series of sinus infections which had gotten worse over the years. Took some antibiotics then, but seems like my sinus issues plus the h pylori infection just made matters worse. Some tests also showed that my white blood cells were low. Also did a hiv test. I have never felt like this before. I know i suffer a panic disorder but these symptoms are nothing compared to the panic attacks.For the panic attacks, the symptoms subside after about 10-30 minutes or so. For 5 months now ive been experiencing a very rapid heart beat which i can see thru my blouse, when seated standing or laying down. I also have constant fatigue, loss of focus or concentration on stuff for a long time and feelings of exhaustion even after a small task. And especially when walking, i get out of breathe. I also had a feeling of numbness on my left hand and tingling and sharp shooting pains up and down my body. I also had chest tightness and sharp pains in my chest too. I thought it was the h pylori but my blood tests for h pylori are now negative after treatment. My blood sugar is normal. My blood pressure is normal according to the doctors, though it has always been a lil bit low all my life- i have a small body frame. HIV test was negative. Though some of the pain, like chest pain and sharp shooting pains up and down went after h pylori treatment I dont know what to do. I have moments of desperation where i feel so helpless and like im about to die and there's nothing i can do about it since the doctors still say im fine. I just feel like giving up on life. Its so frustrating and most of the time i just want to cry. First the panic attacks and now this keep holding me back on so many things. For how long should i have to suffer? My birthday is coming up in a week and for sure i dont feel like celebrating. I'm planning on visiting a specialist soon because i cant live like this anymore.

For several years I would have dizzy and lightheaded attacks, some often other times a month of two apart.   Finally found a doctor that discovered my Potasium Level was on marginal but doctors had over looked it. Now on Potasimn pills and have not had any problems.  Doctor had me go off pills for 5 days and then had an dizzy attack, as she wanted to see what would happen.  I am 82 years young and take Maxide 25 for years and it finally took too much potasium out of my system.  Just a suggestion

I am the exact same way... I used to get like that around once a year, now it's like once a week...

I AM NO DOCTOR BUT YOUR SYMPTOMS ARE FAMILIAR, CHECK YOUR B/P,I AM SURE IT WILL BE FINE, THERE IS PERHAPS ITEMS IN YOUR LIFE THAT YOU KEEP INSIDE THIS COULD BE ONE FACTOR,CHILDHOOD, ETC.  THE OTHER IS AN IMBALANCE IN YOUR AUTONOMOUS NERVEOUS SYSTEM, TRY TO SPEAK WITH YOUR DR. I KNOW HE WILL FIND THE ANSWER, ALSO TRY SOME LOREZAPAM, IT IS ADDICTIVE BUT IT WILL HELP, NO ALCOHOL WITH IT. KEEP ME POSTED. you are not alone.happy new 2013

Well, here I am, thinking I am having a stoke. My symptoms are the same as I have read and have had blood work as well. Yesterday I was at the chiropractor who checked for stroke issues. Once he worked on me my balance was better and my headache was gone. I was told by my GP that I had migraine syndrom yet couold not account for the weakness and off-balance. It happened immediatley as I was walking between concourses at the Charlotte airport and have been with me for a week and a half. Needless to say my heart rate is off the wall if I dwell on it. HELP!!
