So I just got back from a routine check-up with my doctor and she noticed that from last month's bloodwork, my creatine kinase (CK) level was really high: 983. She said it should be around 200, but because I'm working out too much, it's super high and could cause kidney failure if it exceeds 1000.
I do not take any supplements and haven't had any protein shakes for 3 months.
Anyway, I have been working out 5-6 days a week for the past year and I haven't been having any problems. My doctor also asked if I was feeling tired, and I said "yeah, but it's mostly just regular soreness from working out". She thinks its more like muscle damage, so she is recommending me to stop working out for a month. I told her I couldn't do that so she wants me to work out for a maximum of half an hour a day for four days a week? How am I supposed to do that?!? How can I have muscle damage or degradation when my strength is increasing every month?
Is a high CK level a common problem with body builders? What can I do to reduce my CK level and to continue working out without risking any health issues?
