Delayed onset muscle soreness (DOMS) refers to the muscular pain and swelling that follows unaccustomed exertion.
Patients may have an ache in affected muscles with reduced strength 4.
DOMS is thought to occur from reversible microstructural muscle injury that is followed by an inflammatory process and subsequent shifts of fluid and electrolytes. There is usually no permanent damage to muscle function.
- serum CK levels are often elevated
- T2/STIR: affected muscles are high signal and this may persist for months following resolution of symptoms 4
