Most patients do not know how to deal with trauma, or use the wrong treatment, which brings a lot of unnecessary trouble to the future treatment, the most important of which is the common closed injury. Many patients in the first time after the trauma is to rub the injured part, and then use the blood medicine to touch the affected area, in fact, this is absolutely wrong, which caused a second injury. The correct approach is: 1. If a fracture is suspected it must be fixed by clamping the affected part in place, such as a wooden stick or board. 2.If it is a small joint injury of soft tissue, the first thing you should do is to use a cold compress on the injured part, such as ice, etc., and only after 24 hours can you use the medicine that unblocks and activates the blood. 3, immediately go to the hospital to take a film to determine whether there is a fracture. The disadvantages of local rubbing immediately after injury: 1, further damage to the local microcirculation. 2.If it is a pathological fracture (such as tumor), it will cause accelerated spread of tumor cells.
