Here is a letter which describes dysesthesia. Although the sensation differs in distribution, severity, and evoking stimuli, this description captures many of the features which are common in surveyed CP subjects.
Earthshaking news that you won’t believe. Pain hurts. Severe pain hurts a lot. Using gas spectrometry, functional MRI, PET scans, magnetic evoked potentials, retinal dilation scans, and EEG, scientists have completed a 50 million dollar study which concluded that the two synonyms are really synonyms. Another group confirmed this in a stroll through a burn unit. The evidence that pain hurts seems overwhelming. Of course, there are those who keep making this fact a theory, an hypothesis, or even false.
Severe depression is almost the norm in Central Pain. It is surprising that it has largely been ignored. Perhaps the person himself does not realize how much depression is present. Injured by cord injury or stroke and knocked into an incapacitating state with central pain, it is tough to avoid the serious consequences of depression, which rob one of judgment, or even worse, the motivation to follow judgment. .
Because of the persistent comment by CP subjects that the burning feels like “acid under the skin”, (or like the “indian burn” which chlidren give each other) and the discovery of acidifying agents in the thalamus of experimental pain animal models, we have watched reports on acid effects and have reported them. Here is another in that series.
David Bowsher’s criteria for Central Pain have long been utilized by authors at painonline. Now Dr. Bowsher has destroyed ages old theories of where pain is located in the brain. This is the most important and most revolutionary concept of pain in the brain which has yet come to light.
Looking at the paralytic or, if the imagination is in place, listening to the Central Pain patient, it is easy to wonder if Nature and/or evolution has failed man. Why won’t the CNS heal itself.
Central Pain is like a journey without end, really beyond comparison, but sometimes it can support us to hear from others who have had to travel a long, hard road.
We want our normal neurons back, or else to stifle “wannabe” neurons that hurt. It is hard to find an article on brain science without the word “plasticity” in it. Plasticity in this setting means changeability or modulation. Memory itself represents plasticity as new connections allow formation of memories. These connections also facilitate chronic pain. The pain song goes on, long after cells which died are gone, via connections in remaining injured cells, which perpetuate and even amplifiy the pain message. This kind of “growth” we can do without.
