I had a blood test taken recently. It showed for Creatine Kinase 1385. Normal high is 225.I a m not on statins

Question

I have not been doing any exersize and don't drink or do any drugs.
When I sleep at night and sometimes during the day I get severe cramps in my legs from the groin on down. Sometimes in my hands as well. My large leg muscles jump as it the're having an electrical shock. I am at a loss as who go to. I have been told to see a Rhuematologist. But I don't see the connection. Any and all suggestions are welcome. I also feel as if I have been doing a running marathon. I keep running out of energy during the day. I also take vitamin B complex and vitamin E.

Answer 1

Yeah, you should see the rheumatologist. The previous poster is right, the creatine kinase (CK or CPK) tends to go up when patients are on cholesterol medicines, or right after heavy exercise. That being said, an elevation of CK in the setting of fatigue (like you're describing) makes me worry about myositis, usually an autoimmune problem. see the rheumatologist (the autoimmune specialist), and they'll work it up further. Like the prev poster said, it could be hypothyroidism, but I'd doubt it. It's not malignant hyperthermia or neuroleptic malignant syndrome, I'll guarantee you that.

Answer 2

Elevation of CK is an indication of damage to muscle. It is therefore indicative of injury, rhabdomyolysis, myocardial infarction, myositis, myocarditis, malignant hyperthermia and neuroleptic malignant syndrome. It is also seen in McLeod syndrome and hypothyroidism. The use of statin medications, which are commonly used to decrease serum cholesterol levels, may be associated with elevation of the CPK level in about 1% of the patients taking these medications, and with actual muscle damage in a much smaller proportion.

Answer 3

CK levels rise in relation to muscle damage. Heart attacks and other conditions affecting muscles (Rhabdomyalgia) cause elevations of this lab work. Were there any other labs drawn? And why did they draw a CK in the first place? Potassium or calcium levels could be out of whack, causing the heart muscle stress and elevating CK.
