These 5 Symptoms Show a High White Blood Cell Count

Bruising. Bruising happens in those with high white blood cell counts because they do not have enough platelets to block up tiny breaks in the capillaries of the skin. In a healthy person, light bumps tend to avoid bruising because platelets halt bleeding almost immediately, but in those with elevated white blood cell levels, large bruises can develop from even the mildest stimuli. People with this symptom may report that they are not even aware of where they get their bruises from. Gentle pressure can be enough to make a noticeable bruise, and when there is an actual injury, very large bruises can develop. These bruises tend to look like a darkened patch of skin, and they may be any mix of red, yellow, purple, blue, black, brown, and green hues.
