Thank goodness I'm not the only one that has this problem. I thought I was going insane. I click all the time and by the end of the day I start with the sharp pains. Im almost 18 weeks and Ive also got the extra weight problem as well. I was so worried as to how I was going to explain this to my doctor because I had no idea that this exsisted and also didnt know how to explain to him where the clicking was coming from (its a really weird feeling I find). Thanks for sharing this topic.
