Painful symptoms in the patient’s big toe are commonly caused by local trauma and purulent toe infection, as follows: First, local trauma: local trauma, such as a fracture at the end of the toe, can produce severe swelling and painful symptoms. Taking X-rays will reveal the fracture line, and after fixation and avoiding weight bearing, painful symptoms will naturally ease. Second, purulent toe infection: the soft tissue of the toe skin is stabbed by sharp objects, and bacterial infection leads to localized pus, which causes severe swelling, pain, congestion, and even the patient cannot bear weight, and in severe cases, purulent exudation and fever can occur. After routine blood tests, elevated white blood cells are found, and timely treatment is necessary to preserve the bones and soft tissues of the skin, otherwise the toe can only be amputated, resulting in serious adverse consequences, and the patient cannot walk normally with weight, or even participate in sports.
