5. Skeletal problems
Most patients who have NF2 and schwannomas also suffer from bone problems. That being said, some doctors have posed the theory that perhaps the skeletal problems lead to the development of the disease rather than the other way around. If the theory proves true then the formerly-held beliefs that NF2 leads to skeletal problems would be a classic case of reverse causation where one thinks that the cause is the effect and vice versa.
For instance, during the olden days before science was a widely-studied field, some people thought that the movement of windmills generates wind. Of course, we now know that it’s actually the wind that turns the windmills but that wasn’t common knowledge back then. The same phenomenon could be occurring here when doctors think that NF2 causes skeletal problems. If you have schwannomas in addition to skeletal problems then you most likely also have NF2 and thus should receive genetic testing so that you can confirm the diagnosis and get proper treatment for your ailments.
