If the area around the tick bite becomes irritated or shows signs of infection, such as redness or swelling, medical evaluation may be needed. Pus doesn't usually appear, because in most cases tick bites don't cause symptoms. In some cases, the bite area may become irritated or swollen, which could indicate infection. If you notice persistent redness or discomfort, consulting a doctor can help determine if treatment is needed. To reduce the risk of infection after removing a tick, apply soothing calamine lotion on the bite site. This can also help to reduce pain and discomfort.
