Hello, I seem to be experiencing itchi dry skin on my right knee and ankle. Lately the itch and dry skin patch has been expanding. My leg now seems to be retaining water, it is swollen from knee to ankle. Even my foot seems about 2 1/2 inches wider than my left foot. There are two mosquito bite looking areas that are swollen and pressure and discomfort is felt here especially when in hot/humid days or environments.
