In this volume until January 2014 six publications will appear about research done in 1982-1986 including discussion and evaluation based on progressing insight from 1986 up till now. The background of publication is made by the realization that many patients who cooperated to the research can expect something back for their cooperation. Preferably by the regular and modern media but if that is not possible then only by this virtual way which did not exist yet in 1981-1986. These publications provide statistically tested conclusions indicating that chronic pain is not a subjective, elusive phenomenon as was and is always thought. The reason for publication on this site is partly situated in the circumstances that 25 years of research is seen as “obsolete”and not relevant (anymore) and as a result of this can hardly published in the traditional media anymore. Also the judging criteria for research to be developed have been tightened. Legal standards on how to deal with test persons and the written reporting have been drastically changed. Furthermore commercial aspects of the media and interest in “quotation indexes”play a role. Yet the results of the research are sufficiently interesting, still medically and socially relevant to be published. May the reader appreciate the value.

Research results:

1. Chronic pain spots have a significantly lower temperature than their healthy reference points. P<=0.001.
2. Abdominal pain may be related to processes that occur or occurred in the abdominal organs. Visceral-cutaneous reflex ways exist in human in vivo. P<=0.001
3. There is a correlation between pain sensations and found infra-red thermographically measurement information. P<=0.001 Correlation degree 0.69
4. Infra-red video-thermography is a very sensitive diagnostic method (up to physiological level).
5. There is a slight indication that the pain spots are being influenced by the effect of prostaglandins, at which the different NSAIDs do not have a similar effect on the pain spots.
6. Pentoxiphylline has a significantly positive effect on both cold and hot pain spots. P<=0.001
