Detailed explanation-1: -Arthralgia means pain in a joint. Polyarthralgia means pain in several joints (two or more for the purposes of this discussion). Arthritis is a diagnosis and is not a symptom; its diagnosis requires the physical signs of articular inflammation or the physical or roentgenographic signs of osteoarthritis.

Detailed explanation-2: -Most commonly, however, joint pain refers to arthritis or arthralgia, which is inflammation or pain from within the joint itself.

Detailed explanation-3: -People may use arthritis and arthralgia interchangeably, but this is incorrect. Arthritis is an umbrella term for several inflammatory joint conditions, while arthralgia is a medical term for joint pain without inflammation. People with arthritis typically experience arthralgia, but the reverse is not the same.

Detailed explanation-4: -Arthralgia is joint pain. Myalgia is muscle pain. Both can be a side effect of some cancer treatments. Chemotherapy, hormonal therapy agents, and growth factors can cause joint and muscle pain.
