I have been tentatively diagnosed with GPN because of the symptoms I experience each spring. I had an MRI very recently (August, 2015) and the results were normal. This is perhaps not surprising because at the moment I do not have any GPN symptoms.
Each spring going back to 2011, I have experienced the identical symptoms: I get severe intermittent pain in my throat (sometimes radiating out to my jaw). Each "attack" lasts about 15 seconds (although a few "attacks" have lasted as long as a minute).. The pain is very strong---perhaps a 9 on a 1--to--10 scale.
My attacks can be caused by: a laugh, a cough, speaking in full voice, swallowing food---or sometimes the attacks just start on their own: I can be reading a book or sitting at the computer and I will get an attack.
I am somewhat fortunate in that my symptoms have been limited to a 6 to 8 week time period each year (since 2011). The usual time of the year for me to experience my GPN symptoms is mid-March through mid-May.
The symptoms begin slowly: perhaps 3 to 5 attacks in a day. Over the next 6 weeks (or so) the frequency increases--- to as many as 90 attacks in a day.
In the final week or two of the time period, the frequency of the attacks decreases until I am no longer symptomatic.
Once the symptoms go away (for that year), there is no recurrence---I am symptom-free for the next 9 or 10 months. This is where I am right now.
Of course, I am dreading next March (2016).
My doctors have suggested various theories about my intense but limited-time-frame GPN symptoms: allergies, delayed reactions to the cold weather of January and February, fatigue from my job (I am a professional woodwind player in a symphony orchestra and the performance season extends from September through May).
Has anyone experienced the phenomenon of severe GPN symptoms where the symptoms are limited to just a portion of the year---and the symptoms recur somewhat predictably according to the calendar?
Can anyone suggest a theory about what might be causing my condition?
