Question: Hi Doctor, (Can I just say first of all that I ve recently done MRI and CT scans for an unrelated issue and they come up with a big polyp in the left maxillary sinus ). About five years ago, when I was still in high school, I got into a habit of doing this clicking thing at a spot around behind my nose towards the center of my head. I did this very frequently during class and throughout the day just out of habit. After doing this clicking for some time, I got a strange feeling like there was an inflated bubble in the center of my head. Also, I started hearing crunching noises and like little clicking noises spontaneously in my head. I went to a doctor and neurologist , and after describing what i did, they prescribed it as sinus problems, gave my sprays and medicine and I went on my way. I didn t think about it too much at the time, but now I m worried that I could negatively affected important structural parts. I still get the crunching and the clicking noises, and a feeling like a built up of fluid that pops, especially first thing in the morning when I wake up. Is it possible that that clicking habit I was doing could have possibly damaged something? Or can it be the sinus polyp causing the symptoms? If so, do you know what exactly I was clicking or doing? I ve tried and am not able to do the clicking thing anymore. I know this is long, so thanks very much for your help.

Thanks for the answer Dr XXXXXXX I appreciate it. I just want to clarify one point. Do you understand me to mean that I was doing the clicking thing voluntarily? Because that's what I was doing, consciously making the clicking and it made a clicking sound. Could the things you alluded to have been making that clicking nose by me moving them consciously?
And can I just make sure that I couldn't have done anything negative to important parts in my head, like the brain and its associated parts, by doing this clicking thing, even if I did it for long periods of time?
