You must be very special :). I don’t know why that would. My googling said it could be rheumatoid arthritis:

> Rheumatoid arthritis

Popping joints can also occur with forms of inflammatory arthritis, such as rheumatoid arthritis.

High-pitched popping sounds from joints are more likely to be from inflammatory arthritis. Lower sounds can be from either inflammatory or noninflammatory arthritis, although this may be hard to distinguish

...but I don’t think this one symptom could be nearly enough to be evidence of that.

Could just be specific to the joint architecture. Everyone is a little different.

Thanks for the informative reply.

I wonder, the terms we're using to describe sounds are a bit subjective (especially as they are on a continuum). Is there any medical site that gives representative examples of the various joint sounds?
