Is it fair to infer based on this that they are a symptom and not a cause? Or at least, not a primary cause, though their presence may crate a feedback loop?
I would think it is a good idea to assume they are a symptom but could also cause further problems.
Just like sneezing/coughing does occur normally, but is also a symptom of many different health issues, and in the worst cases could lead to broken ribs, etc.
