I took Tegretol for 15 years and all I ever experienced was a TMJ
(temporomandibular joint) problem.  After medication the swelling went
down, but now I have a permanent problem of my right TMJ snapping (a
popping sound, like snapping your fingers) every time I open my jaws
all of the way.

If you have a Dr. appointment scheduled sometime, does he already know about
this?  For the first ~2 years I took Tegretol (and 2 on Dilantin before
that), I had regular bloodwork about each 3 months.  I think some of the
test was to see if the Med. was at the correct level, since some people
flush it out more quickly than others, *but it was also to check that the
Tegretol wasn't attacking Calcium? so might affect Bones and Teeth.
  (My prescription said to tell all Drs. and Dentists I was using Tegretol.
When I told my dentist, he changed my recall from each 6 months to each 4.
I think that was because any Calcium problems might show up first in our
teeth before they're apparent elsewhere.)     I wondered if some of above
might be an indication that the Calcium effects were involved.
  Another place where joint pain might arise is if you might be having
seizures during the Night, but not waking up during a minor event.    (In
other words do many of above seem to be there in the Mornings?  or can the
joint pain you described show up at other times during the day?  If it's
only in the mornings the night time medication level might be wearing off
before morning.  )     G./
