What could be the cause of brown pee, dizziness and muscle pains? - dizziness urine

My husband has suffered from back and joint pain in recent months, feels very tired and exhausted, a few days ago, he began to experience dizziness and chills and dark urine.
We believe that the pains were muscular work, but now we have a little relationship with other symptoms. He is 32 years old, very active, no health problems.
