What does k stand for on a blood test? K is the symbol for potassium. Normal levels are between 3.5 and 5.5 mmol/L. Values outside this range require immediate attention by a doctor, particularly values above 6 â¦.5 where there is a risk of the heart stopping.
Arthritis may also cause excess fluid to build up between joints and may ultimately cause the fluid to form a cyst on the foot. The symptoms of a ganglion foot cyst can vary depending on the individual. The cyst is typically circular with a firm texture that is slightly pliable when pressed.
Ganglion cysts develop in the tissues near joints and tendons, often in the wrists or ankles. They also can occur behind the knees, in which case they are known as Baker's cysts. This type of cyst usually is filled with a thicker fluid than skin cysts. A ganglion cyst causes painful swelling.
