Physical and emotional discomfort can make you miserable. Though doctors can calm itching, they know surprisingly little about its cause. The sensation begins with a stimulus, like an insect bite or sunburn, that tickles nerve endings in the skin called C-fibers. The fibers fire an impulse that travels to the brain, where the signal is translated into an urge to scratch. Below are a list of possible stimulants, how to avoid them and what to do when the itch hits.
Feet are a common site for fungal infections.
Since fungi thrive in warm, moist environments, let your shoes air out after a workout. Wear sneakers with canvas or leather uppers, which breathe easier than man-made materials. Rubbing an anti-fungal cream into the affected area often eliminates the most common form of athlete's foot in two or three days. If white lesions are present, bacteria may have taken over from the fungus. You'll need to use an aluminum chloride solution to clear up the problem.
