hi emma,

the clicking sensation that you are feeling is most definitly due to muscular tension caused by stress and anxiety. i used to get this clicking in my neck/throat every time i swallowed, it would also happen when i moved my neck. i thought it was something sinister and serious and i think worrying over it made the problem worse.

when i started to reasurre my self that it was probably due to tension it did help me break the anxiety cycle. and after about 6 months the throat/neck problems went away. what you need to do is to think positive and keep reminding your self that its all due to stress and dont google any health anxietys because alot of scary stuff does come up that adds to ones worry.

hope that helps hun.
do take care
