Hi,
I have neck problems all the time infact it just constantly hurts and has done for nearly 2 years now, my neck cracks all the time don't worry the crack is just a release of pressure, pressure or as its sometimes refered to, gas builds up in the joints and when there is to much pressure you here the crack thats the pressure being released.
Have you been to a chiropracter over this?
I go once every couple of weeks and it really helps the cracks are less frequent after seeing him and he has done the adjustments, cracking is a good thing, trust me, I know, I also have a (please excuse the spelling) scholieosis (curviture of the spine) and that cracks alot too, infact so does my knee, hip, elbows and shoulders.
I don't think the cracks have anything to do with the AN because all my other body parts crack quite regulary, I think its more to do with the person, my husband hates it when my bones crack because of the sound it makes, he thinks its not right just because his bones never crack, I'm sure if you ask around loads of people have cricky bones or noiesy joints.
Don't worry I think its all very normal stuff and not neccesserly linked to your AN.
Hope I've eased your mind Cheryl. XxX
