My Son Is 20 Years Old And His CK Levels

My son is 20 years old and his CK levels are over 4,000. His liver enzymes are also elevated. He experienced a severe fire ant attack and went tot he clinic. He was told he was also dehydrated at that time. Ever since then he cannot get his CK levels down. He has blood checked every week and no one knows what it could be. He is very fit and has always been active in sports. He did have a torn meniscus and an ACL injury and repair/replacement with a cadaver ligament a couple years ago from a football injury, but no other surgeries. Meniscus was just removed though, no other option for that.
