I WAS CHARGED WITH A DUI IN SC AND LIVE IN NC, ALSO HIT AND RUN.. IT WAS MY 3RD DUI BUT MORE THAN 10 YRS FROM MY 2ND.. WHAT DO U THINK WILL BE MY PENA

I am a lawyer in CT and practice in this area of the law.  If SC's DUI statute has a 10 year look back provision, you may be treated as if a 2nd time offender.  In other words, the DUI that happended over 10 years ago will not count towards assessing your penaly.  In CT, the penaly for a 2nd offender is generally 4 months in jail.  I suggest that you hire a lawyer in SC and resolve the charges.  If you do not appear in court, you can be extradicted back to SC if you are pulled over in NC and the police run your record.

Quite frankly, if you were charged with a hit and run, then any prior offenses will not be as important as they might otherwise be.  You are in serious trouble here.  If there is an accident and/ or injury, then that will be considered to be an "aggravating factor" of the crime.  Therefore, the penalty imposed will be much harsher.

You need to speak with a criminal attoreny in South Carolina as to all of this.  The sooner the better.
