The formation of scars is our body’s natural response to tissue damage – skin scars after surgery or trauma, scarring inside a muscle after rupture. Some scars heal on their own and do not need to be treated separately, but scarring can also lead to additional adhesions between different layers of tissue. These adhesions may be formed, for example, as a result of prolonged wound inflammation. Scarring is a problem if it does not occur enough and the tensile strength of the scar remains low. It is also considered bad if too much scar tissue is formed and this begins to interfere with the elongation of the skin, fascia slippage and joint mobility. In this case, timely scar treatment is very necessary. The scar is often not considered to be the cause of the pain. The human body: muscles, bones, nerves, blood vessels and internal organs are covered with layers of connective tissue (fascia). There are several layers of connective tissue under the skin. If the layers are penetrated by a incisional wound or broken as a result of trauma, the layers of connective tissue will adhere as the wounds heal in different directions. In this case, there is no normal slippage between the different layers, as usual, and the result is tension and pain. The scar can also cause dysfunction, dysfunction of the neck, shoulder girdle and spine, as well as dysfunction of the internal organs. Scars should be treated from 3 weeks to 3 months, depending on their location and condition, for best results. The formation and change over time of different types of collagens is the basis here, and the change and the desired result can be achieved even after a year. It is important to start by evaluating and documenting the scar, and then make a treatment plan and set goals that the patient wants to achieve. The results of scar treatment are usually visible immediately and the change can be significant. Important, which is also noticed by the patient immediately after treatment, is a change in pain and functionality, in the long run also a change in the color, mobility, and shape of the scar.
