Studies have shown that people with higher levels of vitamin D have fewer lupus symptoms. Those living in places where there is more sunlight have a lower risk of developing autoimmune diseases.[12] African-Americans with lupus have been found to have lower levels of vitamin D than Caucasian people with lupus.[13]
In some cases, itchy skin may be caused by complications of diabetes such as nerve damage or kidney disease. Itching of the feet, legs or ankles is a common complaint in people with diabetes that may occur as a result of a period of too high sugar levels. Itching can range from being annoying to severe. Itching can be relieved through treatment, and may be eliminated if the underlying cause is treated.
In some cases, small pits are formed on the skin surface of the ankle. This is formed if the person having inflamed ankles suffers from edema, a condition marked by fluid retention in the body tissues and cells and serous cavities. Long term fluid retention in the ankles causes formation of pits on the skin. In Swollen Ankles fluid retention is the major underlying cause.
