The plural form of algology; multiple studies or branches of the science dealing with pain.
From Greek algos (pain) + -logia (study) + -ies (plural). The plural form reflects how different contexts or subspecializations of pain research might be discussed separately.
Interestingly, you rarely see this plural used because 'algology' itself usually refers to the whole field; using the plural suggests different schools of thought about studying pain, a concept that emerged as pain medicine became more complex.
