back in 1971 at the McGill University by 2 researchers; Ronald

The original McGill pain questionnaire in 1971 had 3 major classes of word
descriptors which were:

  • Sensory – sensitivity, skin colour or temperature changes
  • Affective– how it affects you as a sufferer e.g. fear, tension
  • Evaluative – finding where the pain is

The McGill pain questionnaire also had an intensity scale to determine the properties of pain experience of sufferers.

There are a large number of different pictorial versions of the McGill pain index for CRPS, the Burning Nights CRPS Support version is below:

CRPS / RSD is classed as the most painful chronic pain condition that is known.

It reaches approx 42 out of 50 on the McGill Pain Scale, higher than non-terminal cancer, higher than amputation of a anger without anesthesia…  In some research it has been said that CRPS Type II can reach as high as 47 out of 50.So, why is there not much really known about this terrible chronic pain condition? Why are people suffering from this
burning, stinging pain?

The McGill pain scale / index for CRPS is an important part of chronic or persistent pain evaluation as well as evaluating Complex Regional Pain Syndrome. The McGill Pain Index is also a good way of showing those living with CRPS and their families, friends and loved ones that not only does CRPS exist but is an extremely painful chronic pain condition.
