Lately I've been pulling on my ear and when I do it makes a cracking sound similar to when I crack knuckles or joints throughout my body. First I started just with my earlobe but have moved on to all parts of my ears. Basically i just grab onto whatever part of my ear and pull outwards. This makes a cracking noise. It doesn't hurt nor does it feel good. It just kinda makes the sounds and thats it. I'm wondering if anyone else can crack their ears like this or if its just me. Also I'm wondering if this is dangerous or bad for my ears.

Please don't confuse this with cracking/popping your ears by swallowing and so on... this is something else entirely.
