McGill Pain Questionnaire



.

(1) What Does Your Pain Feel Like?

(2) How Does Your Pain Change with Time?

(3) How Strong is Your Pain?



Interpretation:

• minimum pain score: 0 (would not be seen in a person with true pain)

• maximum pain score: 78

• The higher the pain score the greater the pain.







PHYSICAL DEPENDENCE:-PHYSIOLOGIC ADAPTATION OF THE BODY TO THE PRESENCE OF AN OPIOID. IT DEVELOPS IN ALL PATIENTS ON OPOIDS FOR SEVERAL WEEKS.

THIS IS NOT ADDICTION. WITHRAWAL CAN BE AVOIDED BY TAPERING THE

DOSE OF OPIOIDS.

TOLERANCE IS THE NEED FOR A HIGHER DOSE TO PRODUCE THE SAME PHARMACOLOGIC EFFECT.

THIS TOO IS NOT ADDICTION.


ADDICTION OR PSYCHOLOGICAL DEPENDENCE:-CHARACTERISED BY COMPULSIVE BEHAVIOR PATTERN INVOLVED IN ACQUIRING OPIOIDS FOR NONMEDICAL REASONS AS OPPOSED TO PAIN RELIEF.

INCIDENCE BEING 0.1%.

PSEUDO ADDICTION:-REPEATED REQUESTS FOR OPIOIDS MAY MIMIC ADDICTION.

THIS IS DUE TO INADEQUATE PAIN RELIEF.
