The CPK is often elevated soon after a heart attack. Some muscle degenerating diseases also can be detected by a constantly high CPK level. It is up to your physician to determine the significance of the result. CPK can further be broken down into specific sub-enzymes called iso-enzymes. One is heart specific, one is muscle specific and so on. So if a CPK level is elevated and the cause is not known, testing for iso-enzymes can indicate what body tissue the CPK is coming from.
Boils are very common. They are most often caused by the bacteria Staphylococcus aureus. They can also be caused by other types of bacteria or fungi found on the skin's surface. Damage to the hair follicle allows the infection to grow deeper into the follicle and the tissues under it. Boils may occur in the hair follicles anywhere on the body. They are most common on the face, neck, armpit, buttocks, and thighs. You may have 1 or many boils. A boil may begin as tender, pinkish-red, and swollen, on a firm area of the skin.
In most cases, simple kidney cysts do not cause symptoms and usually do not require treatment. However, in some cases simple kidney cysts can grow large enough and cause a dull pain in a person's back, side or upper abdomen. These cysts can also get infected, causing pain, fever and tenderness. They can burst, also causing pain. Simple kidney cysts rarely harm kidneys or impair their ability to function.
