I have sore throat when I woke up yesterday morning and it feels like a ball in there. But this morning its just a sore throat. And this morning.?

Lots of causes. Is there a fever? Exposed to anyone else's sore throat? Strep or flu or other virus. Salt water gargles can help. Do you snore or sleep with your mouth open? Do you get heartburn? Those can also cause sore throat. If needed doctor can prescribe antibiotics and help with pain.
See an ENT doctor. There are many possible diagnosis from your limited info. You'll need to be examined by an ENT doctor to have your throat and larynx (voice box) examined.
