When you have a higher temperature, you feel weak, which should not be ignored. You need to rest more, giving “extra” unused energy to your immune system, so that it can its job. You should not take antipyretic immediately (usually over-the-counter anti-fever medicine). Instead, let your body combat the bacteria naturally – this also strengthens your immunity.
However, when symptoms intensify, this could mean that the bacteria are too strong (or immune is too weak) and you need external support to help you fight the infection. That’s when antibiotic can be helpful. Ask your doctor whether the symptoms you’re having are mild or strong and consult the possibility of fighting it naturally instead of medicating.
