The suffix "-algia" refers to which of the following meanings?

The suffix "-algia" specifically refers to pain. It is derived from Greek, where "algos" means pain. This suffix is commonly used in medical terminology to describe various types of pain related to specific body parts. For instance, "neuralgia" refers to pain along a nerve, while "myalgia" denotes muscle pain. Understanding this suffix is crucial for interpreting medical terms accurately, particularly in contexts where pain management and assessment are involved. The other options do not align with the meaning of the suffix "-algia", as they pertain to different medical concepts: swelling refers to an increase in size or volume, inflammation is a biological response to harmful stimuli, and "condition of" generally describes a state or category rather than pain specifically.
