There is such a thing as "Typical SD" (AB or AD) - symptoms described in the research over the past decades - and "Atypical SD." Most SD'ers have a "Typical" case but many SD'ers often manifest an "Atypical" set of symptoms.As an example, back before I had neurological vocal surgery for AD, I had what was termed "Extremely Severe Typical/Classic AD-SD." The diagnostician was a 30-year expert, in dealing with SD'ers. We discuss Dr. Herbert Dedo's research/findings at every SD symposium.
Currently, due to having an atrophied cord (surgically impacted), and other severe symptoms (collapsed arytenoids and false cords compromising my larynx, due to over-compensation in trying to communicate, with an atrophied cord and huge glottal gap and no volume), several other world-class SD docs have described my case as "Severe Atypical AD-SD, with PVFM."
As you, I experience severe physical pain (headaches, dizzy spells and severe sore throats/painful throat lumps - coudl be called "popping," etc.) in trying to talk, breathe and swallow.
For "Typical SD," (both AB and AD, without anything else going on) physical pain is not a symptom. However, there are many cases of SD on this BB and elsewhere, which are clearly "Atypical." As we all discuss our symptoms on this forum, it's good to remember how different some of our symptoms are, and how our larynxes behave differently.
Frankly, it's been my experience that "atypical" symptoms are more readily written off by SLP's and otos, because the symptoms are more difficult to diagnose and deal with. "Atypical" cases of SD are extremely confusing for the professionals - not to mention the patients who are trying to figure out how to describe them.
IN such cases, there is often something else, other than pure SD, going on. The more things going on, the more it becomes confusing to a specialist. Patients in an HMO are even more readily written off. HMO's tend to deal with the simplistic. They don't deal with complexity, especially with a severe or atypical case when it's up to the patient to ask for a certain level of attention (testing, etc).
Good luck,
