NMDA is the receptor at the far (brain) side of the nerve synapse which is responsible for long lasting pain. Now the NIH scientists are refining just which part of NMDA we have to worry about. So you don’t have to backtrack through the whole site, we also include a little review of pain chemistry so you don’t have to figure out why NMDA is important. (Skip down to the line if you already remember pain chemistry). Many articles here may be more enjoyable if you take a moment to look at the part of the brain under discussion.

Continuing on the need to avoid stress in Central Pain, we emphasize that any resentment of those who do not understand Central Pain adds unnecessarily to the stress of pain.
