No solution has yet been found as research is still on-going. My teacher's nephew's case has motivated doctors to be active in finding a cure, not only for him but also for those who suffer from this disease. To-date, one small discovery has been made: doctors have discovered the gene responsible for this disease, the BMP4 which is a product that contributes to the development of the skeleton in a normal embryo situated in the second chromosome. After a fetus's birth, this enzyme is deactivated because all the bones are already in place. But for the patients who suffer from this disease, the enzyme does not stop and continues creating new bones, as if the individual was still in the mother's womb.
Because of its nature, doctors often misdiagnose this as cancer symptoms and prescribe medicine not suitable for it, and even increases bone-growth. It is even worse if the patient suffers injuries, as bones patches will instantly form. This means that individuals who have this disease cannot have vaccinations and surgeries, and avoid bleeding and external injuries, in order not to accelerate the mutation of bone formation; making it very difficult for doctors to work on this disease.
Pain in the neck area is common, where the disease starts to take effect. However, not every neck pain means that you have this disease. Although this is not a common disease, it does not mean that it is impossible. The only way to prevent this disease is to research more (and hopefully find a cure one day), share and talk about it to create more awareness so that the more people know about this, the more things will get done.
