3 days after an intense work-out I noticed my urine turned darker. I ran into ER and after some test they diagnosed me with rhabdomyolysis ( CPK over 50.000 )and hospitalized me for 3 days under intravenous (IV) fluids. During those days I was constantly drinking and urinating. When my values doped they let me go home. I repeated the tests after few weeks and the values were normal. Has been over 5 weeks since, and I have notices and increase in my urination. I drink almost 2 L every day however I urinate around 3 (based on my 5 days evaluation measuring my intake and urinate). I have not noticed any decrease in my body weight (actually I have gained 1 Kilo during this month). Shall I be worried?
