i know fanpop is for fun and stuff but this is a health related pergunta and its important.

Is there a bruise where you hurt your hand?

It could be other problems. Maybe your developing some kind of illness, or it could be something like lack of comida and sleep, along with dehydration. Or maybe your just very tired and cold. Usually if you enter syptoms in a health website, it'll narrow down some possible ailments.

Yeah you should eat something and drink something.

You could try exercising if that helps!

First of get a class of cold water and sip it. Don't gulp it as your body will go into shock, sip it.
Put your head between your knees and take deep breathes exhaling mais then inhaling which will calm you down.
Eat a piece of dried toast, if in half an hora you haven't felt sick, thrown up, or became mais dizzy and breathless then another glass of water and another piece of torrada, brinde until you feel normal again.
You're shaky because you haven't eaten anything. It is your blood sugar going 'fuck me compensate compensate!!' (if you will excuse the bad language of course) in future, if you're not going to eat anything drink high energy drinks such as lucozade to keep your blood sugar up.

Going to sleep will also help your body heal itself although i warn you, you will be very hungry and thirsty when you wake up.
I find it helps to keep a few plain biscuits and jug of water por my cama in case something like that happens :)

If the bruise is touching your veins then it might be that your blood is getting around you body properly and you probably need to eat something and drink something
:D hope I helped your welcome :)

Now look at this pic!(cute isnt it?)

You could see a doctor. If the pain doesn't go away then yeah I would talk to my doctor about it.

You should eat and drink something and tell your parents if you havent already.Thats what I would do.

Aren't you too young to drink Coffee?

Eat something, bro.

Do you get light headed? If so you may be aneimic. I have slight anemia.

If you eat and drink as you should, but still feel the same, I would go see the doctor. It's hopefully something minor. If you had a inner ear infection, that could make you feel dizzy and light headed. I would just try to eat, drink, sleep and exercise properly. por all means see a doctor if it continues. Hope you feel better soon.
