Painful Scalp Irritation and Sores
Experiencing an uncontrollable urge to scratch your scalp is a common and distressing symptom of a lice infestation. Unfortunately, the more you scratch, the more aggravated the irritation becomes. This occurs because the lice saliva is spread around by your fingernails, worsening the infection. Moreover, the dirt present under your nails can introduce additional harmful bacteria to the already irritated scalp. Failure to promptly treat the scalp can lead to further complications, including painful inflammation and a worsening of the infection.
Swollen Lymph Nodes
Swollen lymph nodes can be a result of a lice infestation, often accompanied by a low-grade fever. Ignoring the infestation for an extended period can lead to a staph infection. The bites on the head and the spread of dirt from scratching with fingernails can quickly cause irritation and infection on the scalp. If left undetected, these bites can trigger a more severe allergic reaction, ultimately causing the lymph nodes to swell. Consulting a physician is advisable to obtain a prescription for antibiotics, which are typically effective in treating the infection and reducing the swelling.
