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.
These conditions are usually accompanied by symptoms such as chest pain, racing heart, change in vision, and a loss of speech. Dehydration is another possible cause of lightheadedness. This can occur due to various reasons including vomiting, diarrhea, and fever.
