i'm 52 , a couple month ago my neck and my head just started to poo , crack , very discomfort , is there a name for this ? should i worry or tell my doctor ?
Creeking and cracking noises in joints are referred to as crepitus.
You probably have some osteoarthritis in the cervical vetebrae (spine in the neck).
You can mention this when you see your doctor as he may refer you to phsyiotherapy for neck exercises. But unfortunately there is no cure for this. As we get older the cartilage in between each vetebrae (bone) shrinks.
