Fever
The initial onset of arthritis can be associated with fever. This is a symptom that is linked to many different conditions — but don’t forget that arthritis is one of those conditions. A fever develops as the body raises its temperature to fight infection or in response to some forms of arthritis.
If you have taken your temperature using a thermometer, don’t be misled by a normal result after using Tylenol or other medications that can mask a fever. If fever occurs in combination with joint stiffness or tenderness — the clinical picture is developing and favoring a diagnosis of arthritis.
