Hello,
I have no idea if this could be serious or not but recently I read somewhere that it's possible it could be a problem.
For the past few years I've been having these hiccups, they're not really like the usual hiccups where you get them quite rarely and they only last a few minutes. They happen almost everyday but each time only once, I hiccup around 10 - 20 times a day and they don't hurt, its not uncomfortable and there don't seem to be any patterns or reasons as to why I am hiccuping e.g. after eating or drinking. I never thought it could have an underlying issue. I've been told I should probably get it checked before but I'm not really sure.

Thank you.
