Acute osteomyelitis refers to an infection which develops and peaks over a relatively short period of time. In children, acute osteomyelitis usually presents itself as pain in the affected bone, tenderness to pressure over the infected area, fever and chills.
Lotkowski said dizziness is also compared to feeling faint or lightheaded, and may be accompanied by nausea and skin clamminess. A drop in blood pressure which can occur after sitting up or standing too quickly could cause this, as well as inadequate output of blood from the heart.
Lightheadedness occurs when your brain does not get enough blood. 1  You have a sudden drop in blood pressure. 2  Your body does not have enough water (is dehydrated) because of vomiting, diarrhea, fever, and other conditions.  You get up too quickly after sitting or lying down (this is more common in older people).
