ABC = the Australian Broadcasting Commission. It's a TV channel here in Aus.

Also, vegemite is great and I can't believe those of you who are so ignorant of other cultures and US-centric that you condemn a food before ever even tasting or experiencing it. There are culinary cultures apart from your own, you know.

Does it feel as if there is a tensing etc in the joint? Can you feel a possible crack in the making?

I've realised that it's not as much a side to side motion as a pushing my jaw forwards movement.

It's hard to explain but so d**n good.

Well my jaw crack is a pretty interesting one… I definitely don't use my hands at any point, it's just mouth/jaw movement - a side to side rather than opening wide movement.

Usually when a crack is coming on for about half an hour i can feel tension in that joint, and I repeatedly attempt to crack it/tense it by moving the jaw around. Eventually, it finally cracks and feels amazing. Sides crack separately however it's usually my right side (my left is a lot more infrequent). I can definitely feel when a crack is coming on in my jaw, and what side this tension is coming from.

Amazing feeling.

I'm a percussionist, Blaze. Also play a bit of ukulele and piano, but I'm studying percussion. I can relate to getting sore fingers when playing the guitar at first but eventually you develop callouses or at least get used to the feeling of the strings.

The jaw crack is amazing though. It used to happen like once every six months or so and it felt so amazing one day that I attempted to manipulate my jaw just by chewing etc untill I taught myself how to do it - I can only do it once or twice a day now, and for a few hours after each crack I can hear/feel liquid in the joint. Probably a really bad thing but it feels so good.

Well if we're introducing our selves…

I'm Anna, 18, and been cracking for a few years. I frequently do my toes, ankles, back, neck wrists, fingers (particularly fingers coz I'm a musician), thumbs and my FAVOURITE - the jaw. Jaw is so satisfying, I wish I could do it more than a couple of times a day...

mm.

I don't quite understand this thumb thing, but if it gets painful it's probably a sign.
