Mild fever? If I were you if the fever doesn't let up by the end of tomorrow, or comes back is to see a doctor. There are some serious ailments that causes this sort of combination, none of which you want to wait around to see if it gets worse. Or it could be just a simple cold with flu like symptoms, but if it lasts longer then tomorrow you need to see a doctor. But a fever is usually a sign there is a battle going on in your body against some sort of infection and that infection could represent many things so continue to read.
Medications, such as some antibiotics, antihistamines, and seizure medicines can cause these symptoms you mentioned.
Sometime this could represent something simple as fluid overload as well as fluid underload. What color is your urine? If it's as clear as water and your peeing a lot then it's probably overload. Urine should have a slight tinge of yellow for adequate hydration.
On the serious side, fluid overload if your not taking in all that much fluid could be related to heart failure, ortic valve regurgitation, blood clots, chronic kidney failure, and other conditions such as Rheumatic fever, Malaria, Mediterranean fever, appendicitis, certain bacterium associated with milk and poultry salmonella, eggs, meat etc, along with cancer of the blood. Have you been a foreign country lately? Or camping in a wilderness area? If so it's probably related to those fevers or bacterium I listed or others I didn't list. Regardless if it's bacterium from some foreign place you need to call your doc if you experience a sudden, severe, or persistent increase in the intensity of your pulse or the fever continues longer then tomorrw. This is particularly important when this increase is accompanied by other symptoms such as fever, which you have; or when it is not relieved by resting for a few minutes.
If these symptoms don't go away you need to make sure your doc orders the following diagnostic tests:
Blood studies (CBC or blood count)
ECG (electrocardiogram)
Echocardiogram
X-rays of the chest
If you been to a foreign country or camping in a wilderness area you need to tell your doc this so he can run separate blood tests to test for these problems.
Not trying to scare you, but if this thing continues I don't want you to blow it off either. So I'm purposely scaring you so you won't wait to long. A fever lasting more then 3 days is unusual and you need to have it looked at.
