I m asking the questioon for my husband. He had blood tests last week and his CK level is 311. Last test it was only 96. He has had a double bypass in 2005 and is on a statin, blood thinner, etc. He also has a cold and has been taking cough medicine and a nasal spray. He says he feels fine. He also had a nose bleed twiice during the time he had the cold. Do you think the cold and cold medications have affected his llevles?
