What causes a clicking sound in the neck?

Is it bad if it hurts when my neck clicks also I have always struggled with neck pain and lately it even hurts when I move my head quickly also my shoulder hurts aswell

From Saturday I woke up with a bad headache and noticed when I move my head side to side it cracks. I am quite strange normally though and daily crack my fingers, toes, neck, back and chest - I know its disgusting but its got to be done! Anyways woke up Saturday with a banging head and since then when I turn my head slightly to each side it makes a cracking noise and it is driving me crazy, not painful though just irritating. I work at a GP surgery so I casually asked one of the doctors yesterday and he basically said there is nothing you can do its nothing serious it could carry on or stop. It is very annoying though so I am hoping its the latter :-(

My neck cracks constantly when I use my computer. I think it is caused by changing computers - I went from a Mac desktop to a laptop, which is much lower so I hold my head differently after 7 years. I don't worry about it. Don't you either. This is not really a serious health problem.

I've had this for a couple weeks now. And I can even hear it whenever I take a deep breath... a small click in my neck. This is extremely aggravating when I try to sleep at night. As soon as I feel myself dozing off I hear this click inside my neck when I breathe out. I hope I don't have to live like this forever.. oh my god.. it would be unbearable.. There is no pain... just very annoying esp. when i'm trying to fall asleep, and I can hear it every two seconds when I breathe. I was almost thinking of trying acupuncture. I'm not sure what I should do. If anyone has ideas of certain stretches or exercises i'd appreciate any help! Thanks!

My neck would crack every single time I turned my head for the last 4 months. 3 times when I look to the left and once to the right. I tried everything and it would never even improve. About a month ago, I went to a chiropractor and his adjustment didn't help at all but he told me everything is just so tight. All everyone I would see would tell me to strengthen my muscles and his comment got me thinking that maybe I shortened my tendons because I was always stressing with my shoulders up to my ears so for the last month I've been stretching my neck every wich way (mostly straight down while pulling to get more of a stretch on the back of my head) and in the first 24 hours it stopped cracking or clicking to the right and to the left it was only cracking once!! I was so happy but the one click to the left was still driving me crazy!! Yesterday my cracking stopped all together!!! The only reason I can think of is I started stretching my arm straight across me while grabbing it with my other arm and it really hit my back where I'm really tight, I think that stretched out the last tight tendon. My doctor said I would always have the cracking but I'm happy to say he was wrong! BTW the cracking sound in my neck was so loud everyone around me could hear it and cringe, so embarrassing!!
