like the rest of FOP, it's symptoms are few but extremely painful and life-altering.
These symtpoms include:
The main symptom, the gradual displacement of muscles, ligaments, and connective tissue, starts to form at ages 5-10 at the base of the neck and will slowly move down throughout the patient's lifespan. over the course of their life, they will slowly lose all ability the to move their joints and seize up, effectivly turning into a living statue. to combat this, FOP patients often use a managerie of makeshift tools to help them get through their daily life. these can be as simple as a door handle that helps them get dressed, or as advanced as custom order tall shoes and automatic tooth brush.
