In the case of internal bleeding, prolonged blood flow creates a hematoma in the tissue surrounding the blood vessel. This hematoma can become a source of inflammation and thus cause long-term tissue damage. However, if the right treatment is given immediately, the hematoma will be absorbed faster and the inflammation will not cause serious damage. For this very reason, timely administration of the treatment is very important.
Although we cannot see the hematoma itself, we can understand its presence from the "effects" that brings to the tissue.
Contusions (big bruises), edema, skin heat, pain, numbness and restriction of mobility of a joint, are all indications of internal bleeding.
