Do warm saline gargles and also steam inhalation.
If you have or get fever you could take a paracetamol. That's all we can say as of now from the limited history that you have posted here.
We are not supposed to suggest medicines on this forum as it will be illegal to do so.
And moreover, without examining the patient, it's very difficult to say what medicines to be taken.
So if you still don't feel better, Consult a physician in person.
