Yesterday I woke up w/ sore throat felt like a ball in there but this more just sore throat. Should I be worried?

Probably not. Probably from post-nasal drainage. Try some nasal saline spray or rinse and an antihistamine (benadryl, zyrtec, allegra, etc). If it worsens, fails to improve over a few days, or you start running a fever - see a doctor.
