Click click click

This is my little companion.
For the past month wherever I go, the little fella goes.

Call me crazy, but I've been keeping a record of the clicks and cracks of my right TMJ.
On my last medical appointment with Mr. C. I was told that if my current condition does not improve until January, another surgery may be considered to recapture the disc. Straight after that appointment I started paying more attention to my TMJ clicking and crepitus - what kind of clicks it makes, when does it click, how many times it clicks?
If I want to know exactly how my TMJ is evolving (if it is getting better or worse), keeping track of the two main symptoms - pain and clicking - may help me understand. However, pain is very subjective and quite hard to quantify. It depends on a long list of factors, and each person feels it differently. Taking pain medication constantly makes pain quantification even more difficult, as it masks the real symptoms. Quantifying clicks is a lot easier and requires only two things: a tally counter and a notebook. Every time my TMJ clicks, I click the counter. I take note of the number of clicks before the two main meals (lunch and dinner) and in the end of the day, covering the morning, afternoon and evening periods. For the same time intervals I classify my TMJ pain from 1 to 10, according to this table.

Because my disc is anteriorly displaced, the TMJ clicks upon mouth opening. This doesn't mean that whenever I open my mouth, the TMJ clicks. A lot of times it doesn't - it depends how wide I open my mouth, how much pressure I am putting on the TMJ, what I am doing (biting, chewing, swallowing, talking), what I eat, etc. However, taking into account that my days are pretty much the same, following the same routine, soft-food dieting, talking and laughing roughly the same amount each day, the daily sum of clicks should remain around a certain value. It is only based on this assumption that I can compare different days and trace an evolution trend.

There are different kinds of clicks. The ones I get the most only I can hear them, although they are easily felt when pressing a finger on the joint. Louder clicks (or pops) are less frequent, and can be heard by anyone standing up to a few meters away from me. They sound like fingers being cracked or chicken leg bones being broken. The loud clicks produce an immediate relief on my TMJ discomfort, just like a dislocated bone being brought back into place. Unfortunately it is a temporary relief. Crepitus is always present whenever I move the lower jaw, a continuos grating sound - the reason why mouth movement is not smooth and feels like a old wooden door being open. I only count clicks, not crepitus noises.

So far it looks like this:

Fitting a trend to the data, it appears that the amount of clicks is increasing with time. But what is the significance of this? Could my TMJ be gradually getting worse?
As for the pain, I am slowly increasing the amount and strength of the medication. Sometimes it aggravates after a major click - I feel a pulsing electric pain spreading from the TMJ towards the rest of the face and head. Could be another sign of worsening... Could be due to the "great" british weather...
What do you think?
