To get the reasearch further into perspective I say the following, too.

About 40 years ago when I was at school and walking a fair bit, just 
occasionaly my shin muscle would not work too well and the foot would go 
flap on the pavement. That happened to my father, too, when walking for 
the bus sometimes.

About a year ago when I walked up and down a big hill I started to get 
less sensation over the left shin muscle for some days after.

So it seems I may be running out of some nutrient for the nerves. Perhaps 
the dental injections just take the situation past a recovery point.

The flash of sensation in the left forehead some seconds after the upper 
6 molar is anesthetised sort of makes me think of the ringing sound in 
the ear from a loud noise which does not go away again properly. Perhaps 
it is that and not to do with any formocreosol.

The sensation is not terribly unpleasant but I get the feeling the motor 
nerves around the eye are starting to be involved, as with the left lower 
lip.

I have thought before that the trouble is happening somewhere in the 
cerebellum. Maybe it is in several places.

Things are a bit complicated by the severe pain with some radiation that was 
there before the root dressing. Maybe the nervous system makes its own 
opiod substances relating to nerve damage even if the pain is not there.

In spinal injury the nerve damage continues after the initial trauma. I 
wonder if that happens with dental injections and myself in some sort of 
similar fashion.
