Exercise-induced rhabdomyolysis symptoms

Rhabdomyolysis happens when damaged muscle fibres release substances into the bloodstream. It can appear after unusually intense exercise, especially when the body is not accustomed to the workload. Soreness after exercise is common, but rhabdomyolysis is more concerning when pain is extreme, weakness limits normal movement, swelling feels tense, or urine becomes tea-coloured or cola-coloured.

Stop the workout and do not test the muscle with more exercise. Rest, avoid alcohol and non-prescribed supplements, and arrange urgent clinical assessment. A healthcare professional may check muscle enzymes, kidney function, urine, hydration, and possible triggers. Do not rely on the absence of dark urine to rule it out, because symptoms can vary.

Go to urgent care promptly for severe muscle pain with weakness, marked swelling, reduced urine, dark urine, vomiting, confusion, faintness, or trouble breathing. Emergency help is appropriate if symptoms are rapidly worsening or you cannot walk safely. Delaying assessment can allow dehydration or kidney problems to develop.

Ask whether your symptoms fit rhabdomyolysis, which tests are needed, how much fluid is appropriate for you, and when activity can restart. Mention recent exercise intensity, heat exposure, illness, medicines, and supplements.
