I believe "lidocain" is similar to novacain, which is used for numbing our
gums when we visit the dentist. Several years ago, I had around eight shots
(all at one time) covering about a five inch area in my upper back to relieve
pain. It was tremendous for relieving the pain. My back didn't hurt for over
three months. Apparently, when you have a large area, they use lidocain
injections instead of cortisone, which is for a specific area/joint. However,
immediately following the injection, I had a reaction to the medication and
was blacking out when I tried to stand up. I laid still for over two hours
and felt all right so I got up to leave. While waiting to pay my bill I
blacked out again at the desk. Wound up spending over four hours in the
doctors office. So, I don't use "lidocain" when I go the dentist or allow it
to be used for any other reasons. Later, I had an allergy test to find
another form of "novacain" as there are some circumstances which it must be
used.
I'm not sure if I had this reaction because I became allergic to the
medication, or if having eight shots was too much for me at one time.
Hope this info can be of some help.
