Trismus that is radiation caused has to do with scar tissue forming in the fibers of the muscle as a result of the radiation damage.

What this article is talking about is transient trismus, which is not the same thing. If Tums worked for a head and neck cancer patient (calcium supplementation) along with warmth applied to the area, it would not be one of the worst permanent quality of life issues that H&N cancer patients deal with.

As with other sites that are covered with ads for things somewhat related to the topic, most of them just ways to separate you from your money, I wouldn't trust any site that is coved with paid ads. As OCF is a mamber of HON Code- Health ON the NET - (see the badge on the bottom of our OCF home page and you can click it to show that we are current), we do not allow advertising on our site, for very good reasons. Go to a web page covered with ads for bogus nonsense and you are getting is some bare bones information (of questionable value most of the time regardless of subject) designed as a vehichle to mount ads on, not to provide you with the most scientifically and clinically proven information you can get.
