Official (IASP) definitions of pain terminology: reading so dry it’s like eating a bale of hay! But a valuable reference nevertheless. For example, here’s the formal definition of pain:
An unpleasant sensory & emotional experience associated with actual or potential tissue damage, or described in terms of such damage.
And now less formally, my translation:
A shitty, freaky feeling which may or may not have anything to do with fucked up tissues (but it sure seems like it!)
I should do a complete translation of the entire IASP taxonomy page like that.
