<s>[INST] Why do we get fevers? [/INST] A fever is a perfectly normal physiological process and immune response. If you have a fever, it simply indicates that your body is fighting off some kind of foreign invader. Scientists are still working to understand why elevated temperatures are such an important part of our immune response.

Most of the fevers you get will be from a bacterial or viral infection. We often see fevers with upper respiratory infections such as flu, urinary tract infections, and even skin infections. When you get sick with any kind of bug, your illness is usually accompanied by a fever.

You can also get fevers as an allergic response to a new medication. These fevers are known as “drug fevers”. While many people who are allergic to a medication will develop hives, fever is another common response. If you have a fever due to a new medication, you usually don’t have any other symptoms and feel otherwise fine. These fevers usually resolve themselves when you stop taking the medication.

Many autoimmune diseases will also present with recurrent low-grade fevers. These fevers will come and go and are usually accompanied by fatigue and muscle aches. While a low-grade fever is no reason to panic, it’s worth seeing a doctor if you have a fever that seems to keep coming back. Source: MED HELP CLINICS.
