Fever that won’t go away – should I be worried? - #22

Anonymously

I’ve had a fever for the past five days, and even though it goes down with medicine, it keeps coming back. There aren’t many other symptoms except feeling tired and achy. When should I worry about a fever that lasts this long? Could it be a sign of an infection that needs antibiotics, or should I just wait it out?

A fever that keeps recurring could be a sign of an ongoing infection, but it could also point to other conditions such as viral infections, inflammatory conditions, or even autoimmune disorders. The lack of other symptoms (like cough, rash, or digestive issues) doesn’t completely rule out an infection, but it’s important to get it evaluated.

I would recommend seeing your doctor to rule out any serious causes. They may want to perform some blood tests, including a complete blood count (CBC), to check for signs of infection or inflammation, and potentially test for specific viruses or bacteria. In the meantime, try to stay hydrated and get plenty of rest.

While this can feel concerning, many fevers can be managed with appropriate treatment once the underlying cause is identified. Your doctor will be the best resource to guide you on the next steps.
