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

get your parathyroid checked. It can cause allot of those symptoms. I too was test for Pheo Chromo Cytoma but it came back negative.

This may be a stretch but my daughter had some really weird symptoms going on for months before finally being diagnosed with POTS (Postural Orthostatic Tachycardia Syndrom).  It has a variety of similar symptoms.  One thing you can check is blood pressure while laying down, then again when sitting with feet on floor, and again while standing.  In a person with POTS typically their heart rate will increase 30 beats per minute from the laying down position to the standing position.  It can cause extreme fatigue, dizziness, near blacking out (some people do black out) racing heart rate, flushing of skin, migraines, etc. etc.
I am so sorry for what you are all going through.....I know how frustrating it can be going back to the doctor over and over again and feeling like they don't think anything is wrong ...even feeling like maybe they think you are imagining it!
Don't give up.....keep searching for answers.....on the internet and new doctors if needed.  Eventually you will find the cause.
take care

I am 27years old, never had any major health problems but now that I am working on gettin depression & anxiety along with those wonderful migraines under control I have been having some really strange sensations.   See about 1 1/2 yrs ago I was sent to a neurologist to do some different test because we were concerned about some tingling in my fingers, well no symptoms or signs since back then.  A little over 2wks ago, I ended up in the ER with a migraine so bad I was so sick.  I tell the ER nurse that i was tingling in my fingers & lips, she says oh just calm down, its called anxiety.  Well trust me, if that was the case, if anyone truly new the stress in my life at this point, I would have had it everyday.  Then last week on wed. while at work, I was lightheaded all day long, eating, checking BP having sugar NOTHING seemed to work.  I had to deal with all these feeelings all of you are talking about allllll day long.  Now this weekend is the first wkd I have been able to totally relax and enjoy, well of course yesterday afternoon I get all these feelings again......this morning wake up with them alll...cant even enjoy a great wkd w/ the girls, what the heck am I supposed to do???? I can not k=live like this being I work in a pediatricians office, have 3 boys of my own and a husband.....come on....anymore advice???? I dont know what to do, I am tired of all the blodd test and tehy come back negative, the neurologists cant find anythng, not that I want something wrong.....I just want to FEEL better and be able to function everyday.....HELP ME PLEASE!!!

HI!!!I know what you guys mean...Eversince my freshman year in high school, i have had various symptoms and no one knows what it is. It started when i was in Gym class. I got lighheaded, my head started to heart, my heart was pounding(because i was running), i was dizzy, shaking , shortness of breath and so forth, and i looked pale...Anyway i thought it would go away that it might be because i was out of shape and was not use to working out...Eversince it has happend to me multiple of times like tons of times...HOwever, my heart is not punding, but i get dizzy, headache(which runs to my eyes), shaking, my whole body feels week and in pain...but i could not describe what kind of pain its just such a weird sensation that i have no words to describe, also i shake and so forth.... I have gone to the doctor many times and no one tells me anything, your heart test, brain test, blood, test all is fine... It might be that your not getting enough oxygen/liquid to the brain and thats why i get all that...OK? And how can i make that better...no one knows...For a while i though it was my sugar, a drop of sugar in my body, but know not even sugar really helps that much...Its been over 4 years now, now i am a freshman but in collge, and still i get this and no one know what it is. This is often and i am scared that it might affect my work(beacuse i am so weak and so much in pain) that i just cant go and my school as well, i miss college and i just dont know what to do..
Today i am going to the doctor and telling them everything and this time they better have an answer....Today i am home feeling like this, and researching because i am not about  to live my whole life like this, i am just 18...Also gentlemen that said that he thinks it might be something of minerals and so forth...i agree i was researching and anemia causes alot of the things i have....and researching into anemia...its something that it might be linked to...And if any of you know what this is please let me know what i can do because this is horrible...
Good Luck to Everyone!!!

I have also been dwelling with similar symptoms and no one can figure it out with me eather

I am 28 years old, I have all the symptoms you guys have, last Saturday, I have the same problem again, this is my third time. I felt dizzy,  shortness of breath, cold and pale face, my hands and feet numb and muscles cramped. The first time when I had this problem, I went to ER, unconscious. But all my blood tests and other tests are fine. I was a professional swimmer, no other illness. I am worry about that I may have some kind of serious sickness and disease.
When it happens, even I eat food and sugar things, it doesn't work at all. Laying down helps. I felt no blood and oxygen go through to my brain.
I hope someone can find the solution to fix our problems.
