a few years ago when i was still able to work ,i went under a car and leaned my head way back off the end of the creeper,i got VERY naushes,rolled out and it went away after a while,i think i had my head bent back to far and it cut the blood supply to my brain
my spell checker dont work on that word!!
im now 76

I think its something you ate, but you should probably go to a DR and spend a few thousand dollars on some tests and have the Dr tell you it was something you ate. Gene

While possible, I kinda doubt it because of how it happened. If it was food related, it wouldn't care if I was laying under my truck.

As with anything medical you should always get a second opinion:

You could have Hot Flashes or Hemorrhoids.

Only time I get nauseous working on my junk is when I realize how much money I spend on it.

If you were lying down at floor level in garage/shop: be very weary of any possible "fumes" that will settle down low. Had it happen to me once/twice. Under car working just wrenching: got upright, dizzy/headache bad. Cleared after walking around/sitting. Happened day or so later.
Same. Then days later, while moving stuff around, found a qt can or urethane paint that had tipped over, behind some stuff out of sight at floor level. Didn't pour out, but rather just slightly oozing from lid. Apparently the fumes from that weren't enough to outright smell, but over time lying there must have breathed in enough to effect me. Thought I was having a stroke, felt so bad. Wised me up abruptly about solvents in a shop while working. So be safe out there guys.

i would go to a doctor right away.maybe he or she will at least give you some stupid pills when you tell them you were on Moparts asking for advice.

This is fairly common and something that stays with you your entire life.

Please do and Keep us posted, Better yet, call them today

a new virus out of detroit-----car-anus virus.....

Maybe dehydrated? Hope you are all right. Doesn't sound like "old age".

Suck it up and drive on, next Dr apt bring it up, do your yearly blood work and see whats up or whats not up.

I can see there is a wet noodle group that runs to the doc at every hicup that dont taste right but dang your 50, hell it could be even emotional. Just like old people sex changes ALOT that doesnt mean anything is wrong, were just aged a bit.

Go find a nice shade tree and put a blanket down and plan a nap, tell us if that action or thought makes you sick?

Maybe its these dive food joints your going to and your getting hit with the bad meat sweats and all that comes with it, who knows but with what your describing id just bring it up and keep up on your blood work.

Next time your feeling that way, think of your ex wife and let us know what happens.

You need to change your screen name to Feets2, yall always got some craziness going on.

Do you have a pet?

Sudden unexplained outset of Nausea for two(?) hours, the second occurrence out of the blue, in over a year, ought to get everybody's attention, except for the hold my beer crowd, the anti better to be safe then sorry believers.

Surrre....

Hope you read this before the edit JCC, it was just for you.

I'm a little older than you are and I have never had those symptoms you've had. Lots of other medical issues in my life but not like yours.
If I was you I would be seeing my family Dr. ASAP, you know it isn't going to go away quietly, correct
No one wants to here bad news, especially the persons family and survivors when the Dr. says if only they had detected the problem early
I lost a good friend to a Dr. who didn't do enough testing on a sinus problem, the Dr. ASSUME he knew enough to treat and his lack of attention for better diagnosing and testing allowed the cancer to grow and ended up killing my friend

Well, "Hope springs Eternal"

Peace.

Could be a simple inner ear or sinus related problem since it only happened why you were laying down.

Dehydration and a lack of potassium in your body can make you feel dizzy too.

I talk to the Doctor tomorrow at 8AM.

I don't think he was asking for advice looking back at his post. He simply asked if anyone else experienced this. Go back and read the original post. My father an older guy, has not been able to work under a vehicle for quite some time and experiences the same thing as described. He's still alive and well.

SOMEBODY got it. You are correct! Some people just like to pick.

Thank you.
