About a year ago I had a root canal done on my rear, left, bottom molar,
which also required the rebuilding of  large portion (including below gum
line) of the tooth due to a long period of decay.  The tooth was capped
shortly afterward.  At that time, my dentist also noted that one of my lower
front teeth would also require a root canal (x-rays showed a slight dark
area at the base of the tooth).  As I can only afford so much dentistry each
year, this tooth has yet to be treated.

A while later I started getting some sinus problems (felt like post-nasal
drip) and my throat would occasionally bother me (tightness, "lump in the
throat" feeling).  Over the next few months the problem would come and go
and was only a slight bother.  The past few months however the problems has
become more pronounced.  Also I've started to feel tired and a little weak,
with occasional slight light-headedness.  As well, I'm occasionally getting
a tightness in my jaw (no difficulty moving my jaw, just a feeling of being
taut).

I recently had a specialist check out my throut.  He found nothing
physically wrong after looking down my throat.  As I have been under some
stress for the past couple months due to my mother being diagnosed with lung
cancer and her recent passing, he suggested that I was experiencing throat
muscle spasms due to stress.  Apparently this is quite common and usually
subsides in time.

However, I'm not convinced my symptoms are unrelated to my teeth.  I will be
consulting my dentist soon, however any suggestions here would be greatly
appreciated.
