Sometimes when I touch my external auditory canal I get hiccup. I first noticed it when I was 15 years old. I'm now 22 years old and it is still happening. I have it periodically, meaning that I can touch my external auditory canal and not getting hiccup for months. But then it appears again, I don't know why. For instance I'm suffering from hiccup since about 20 minutes now, because I cleaned my external auditory canal. It's quite annoying! I've once read that many people react by sneezing when their eyes are exposed to a light of big intensity. Maybe it's related to my "problem"? I've searched on the Internet about hiccup and ear, and never found anything like I described. Is it normal at least? Do you experience the same? Edit : I found something : from http://www.straightdope.com/columns/read/1113/what-are-hiccups-and-why-do-we-get-them : Strange. Edit 2 : I'd be glad to know why it happens. The phrenic never doesn't seem to be linked to the eardrum at all.
