The bruise is accompanied by a lump inside. Generally speaking, the common clinical causes are mainly the following: i. The local bruise is large in volume and may be accompanied by the formation of local hematoma. If the bruise bleeding does not stop and shows a trend of progressive expansion, a local ultrasound examination needs to be improved as soon as possible. The size and scope of the hematoma can be clarified, and skin incision can be performed as soon as possible to remove the local hematoma and stop the bleeding completely within the trauma, so that the local mass can be removed more quickly. Second, if the bruise is accompanied by inflammatory granulation tissue formation in the process of self-repair of the body, local lumps can also be formed at this time. For inflammatory granulation tissue, we can use the methods of external application of hot amyl pack, external application of blood circulation and stasis cream, infrared local physiotherapy and moxibustion strip fumigation to improve local blood circulation and promote faster absorption of local lumps, so as to achieve better results.
