ever since I was a little kid, whenever I get a cold, I get largynitis and it always lasted for weeks. Hoarse or no voice. And I usually got colds that seemed to last all winter long.Last winter I stayed healthy all winter long for the first time in my life. This winter, I caught a cold, lost my voice, it never came back and I now have AB/AD SD.
From what I've read, there isn't a causal link, but a coincidence link. In other words, SD frequently starts after an onset of largynitis, but isn't caused by the largynitis.
