In many cases, exostosis is asymptomatic and also can be painless. In other patients, exostosis will often cause chronic pain depending on the location of the growth. The level of pain will vary from person to person and from growth to growth. Some instances of pain are generally mild and can be relieved with rest or over the counter pain relievers. Other instances of pain are so severe as to be debilitating.
The location of the lesion plays a big role in the amount of pain a person will experience. Secondly, the size of the growth and its shape will also play a part in how painful the growth may become. Some lesions grow on areas of the body that are in constant movement or those who experience a lot of friction on a regular basis.
Due to the pressure of the growth in neighboring structures, surgical removal may be the only option.
