as far as I can find, paracetamol is only for reducing pain - it is not antibiotic.
If you can, please go to a doctor. In the meantime, take a decongestant to reduce pressure in the ears, and use a small amount of garlic oil to try to reduce or prevent infection.
I would advise you to see your doctor.
It does sound as you have either a viral or bacterial infection.
Your ear needs to be examined to see it that is infected so that the appropriate medication can be prescribed.
Best wishes.
