It ain't broken to the point where it needs to be fixed.
It can get really severe and painful, or so I've heard, but I have a very mild case. Pretty much the extent of it is that I have somewhat limited chewing endurance (I don't really care much for gum because of it), only really noticeable with gum or beef jerky, and my jaw pops whenever I open my mouth.
I don't think it's related, but my mom pointed out to me that I can't swallow large amounts of liquid. If I drink a mouthful of water, it takes probably 10 swallows to get it all down.
While we're on the subject of weird medical issues, I have glasses and poor eyesight but I can see well without them, I just have trouble focusing.
People may find it disgusting, but I find it amusing - I unwilling regurgitate food. Mostly veggies and cold dairy products, but other stuff has come back up. The doctor says that there's a flap at the top of my stomach that doesn't work right, but isn't really a problem. It means I can eat a bowl of ice cream and enjoy it over the course of an hour.
I am right handed, but I form my letters the way a leftie does, which made learning cursive in elementary school a complete bitch. Apparantly, normal people start their letters from the top of the paper and go down, I start them at the bottom and go up. The english language wasn't designed to be written from the bottom up. n, m, p, and several other letters and numbers are difficult for me to write. Note how when you write them, you start at the top, go down, and go back up, making the first line a double line. Try doing it starting from the bottom. It doesn't work.
Now, from when I began writing in elementary school, until a few months ago, I thought that I was just weird. Then somebody saw me writing and pointed out that I write like a lefty.
