Hi there I understand your concern... Typhoid fever should be treated with specific antibiotics if you are already on antibiotics nothing much to worry just continue symptoms will reduce by the end your antibiotics course... Take paracetamol 650mg thrice daily...drink plenty of water...This helps prevent the dehydration that results from a prolonged fever and diarrhea. If you're severely dehydrated, you may need to receive fluids through a vein ...if no improvements consult your treating doctors they will guide you further.
