What are common signs and symptoms in a client with lice?

Pain and blisters are not characteristic of lice infestations. While severe scratching can lead to secondary infections that may cause pain or blisters, these symptoms are not directly caused by lice themselves. Lice primarily induce itching rather than pain or blistering.

Sores may develop from scratching due to itching caused by lice, but headaches are not a typical symptom of a lice infestation. The presence of sores can indicate secondary infections but does not reflect the primary symptoms associated with lice.

Cyanosis and dizziness are unrelated to lice infestations and suggest more serious medical conditions. These symptoms are typically associated with respiratory or circulatory issues rather than parasitic infections like lice. Lice primarily cause localized skin irritation and itching.
