Chiropractic is a health care method of manual moving (“correcting”) affected joints, ligaments and muscles, especially the spine and its effect on the nervous system. The main goal is to eliminate pain and improve the flexibility of the moving system. Functional blockages in the cervical spine cause difficulties as headaches, dizziness, and feelings of insecurity, vomiting, eye pressure, and neck and throat tension. Before any chiropractic treatment, it is necessary to exclude any internal and surgical illness (as heart-attack, acute abdomen).
