Pink eye, sore throat, fever and enlarged tonsils. been having reoccurring infections for a few weeks but this is the first ever case of pink eye. last week had antibiotics for fever and throat infection but came back. what treatment is best here?

This could be an infection or an allergy problem, or both. That conjunctivitis (pink eye) is now part of the problem isn't very surprising or alarming, either for infection or allergy. There isn't enough info for any distant forum to recommend the best treatment. Ask your doctor about referral to an otolaryngologist (ENT doctor), or perhaps an infectious diseases or allergy expert. Good luck.
