A hard lump on the bottom of the foot with significant pain when pressed is more likely to be fasciitis or fascial cysts, which have a very high incidence and are associated with prolonged strain. In addition, local soft tissue contusions or bone contusions caused by trauma are also prone to this complication, which can also lead to increased pain when the patient is active. In severe cases, further surgical options are needed to remove the cyst. Mild cases can also be treated with local closed injection therapy or oral NSAID application of celecoxib, which can also relieve the patient’s condition to some extent. The patient should be careful not to put on weight or strain, because too much activity can lead to swelling of the lower limbs, and the lower limbs can be elevated in the lying position to promote venous blood flow. To a certain extent, it can also improve the patient’s pain and discomfort, and pay attention to regular checkups.
