My throat starts to hurt whenever I sing (like a dry, scratchy throat). Im far from good...this is just singing along with the radio. What could I be doing wrong?

You may be dehydrated from not drinking enough water or drinking too much coffee. Drink a glass or two of water and wait 20 minutes before singing. Also, warm up your voice first by humming along for the first ten minutes instead of going at it full pelt straight off.

You should not speak loudly or sing without first warming up your voice/throat. Search online for simple vocal exercise videos, just a couple of minutes will make a difference. Even if you are singing just for fun, losing your ability to sing is not fun. Trust me, I know. Enjoy!

its a common thing if you don't sing very often. your throat is experienceing a foriegn feeling and only practice will make it feel natural

Your throat can't handle the notes you're singing. If you want to sing, sing quietly don't belt it out since its like pushing your muscles too far.

Smoking can cause this.

Do you have allergies? Are you well hydrated? Do you have carpets at home? Read these questions and you may find your answer.

maybe the song key doesn't fit you..

you're a girl so the problem probably has something to do with your break (when your voice changes from strong chesty voice to your head voice). This used to happen to me a lot- you're straining your voice! Don't sing loudly if your throat feels like this. Instead of singing through your nose or forehead, you're singing through your throat. Try singing with your head voice (although this may be weak, by practicing using it it will become stronger) instead of with your chest. Don't try to reach for high notes using your chest voice either- this can really damage your voice. Think of the sound coming out like a laser between your eyes and the power coming from your abs, not your throat. If you sing like this, it will take pressure off your throat- it will soon become natural to you and your throat won't hurt when you sing! Good luck!

It's gods way of punishing you for that horrible noise you call singing.

It sounds to me like a combination of things... firstly, you might consider going to an Ear, Nose, and Throat Doc because it sounds like you may have a vocal cord problem. However, it is likely that your problem is just a matter of incorrect singing.
It really doesn't matter if you're "good" or not...poor vocal technique, singing too loud, singing outside your comfortable range, screaming along with metal or screamo music... these are all things that can damage your "pipes" so to speak.
A good rule of thumb... if you're singing and it starts to hurt, STOP. Keeping your throat properly hydrated is also helpful!
Good luck!

you are most probably straining your voice..

Maybe you are dehydrated. If you have nasal allergies, they can also interfere with your ability to sing. Drink plenty of water. You can also take a shot of lemon juice right before you sing and that should help (I've seen performers do this).

Perhaps you're just dehydrated or something minor like that.
OR, you're not singing correctly.
You could be straining your vocal chords.
You should sing with your diaphragm.
When you sing, don't let the air out.
Keep it in you stomach (so, you actually have to use the muscles in the stomach) and just push the sound out, not the air.
A vocal coach helps a lot if you're considering that.
You can be taught the correct way to breathe and let the sound out when you sing :D

It sounds to me that you are most likely singing from your throat, which is not good. Usually when a person sings from their throat it doesn't sound correct either, but again if you are just singing along to the radio it'd be a little silly to tell you to sing properly from your diaphragm and all that just don't try to belt or scream and take it easy on your throat, because that can lead to damage or voice loss.
