A month ago i had a throat infection, full fever, nausia etc. was given antibiotics which cleared it but now have recurring pain when i swallow.?

Tonsils inflamed: The throat infection may have been incompletely treated, leaving a low population of bacteria within the spaces or crypts of the tonsils, and after the antibiotics are no longer a threat, repopulation can occur. This is how chronic tonsillitis develops. Chronic inflammation of tonsils is common in those who have deep pockets or cryptic spaces in the tonsils.

SEE YOUR DOCTOR: If your throat is still having pain, then you need to see your doctor.
