The medical term for itching is pruritis, but it may as well just be called pure agony—that's how exacerbating the sensation can be. One frequent target of itching is your feet, which are subject to a great deal of stress and susceptible to a variety of conditions that cause itchiness. For instance, your feet are exposed to temperature extremes from your shoes and the physical stress of bearing the weight of your body. This can cause skin dryness and irritation, which are common triggers of itchiness. Even though scratching is a normal response and temporarily relieves an itch, it often makes the skin problem worse and can even result in a secondary bacterial infection.
Of course, no one loves to have an itching sensation, but at the bottom of your feet make the scenario even worse. Since your feet can be repeatedly exposed to floors, grass, damp weather and sweaty footwear, all these things can be the cause of irritation of the skin. Itchy feet are also the signs of either a skin condition or some other underlying disorders that may cause itchiness. It is caused by the fungal infection which affects the skin of feet and can spread to the toenails. Walking barefoot in the grass, damp closed rooms like locker room can increase the risk getting this infection. Uncontrolled diabetes is the one of the common cause of such neuropathy.
It is caught through walking in the sand after an unwormed cat has done its business there and then the worm pierces your foot and works its way around quite revolting! I have posted this as I am sure alot of other people have caught it and my GP had no idea what it was. It starts with a very itchy foot, then you will see telltale track marks where the worm is moving around!
