Itchy skin is normally caused due to excessive dryness of the skin. However, the kind of itchiness you are describing is quite unusual, simply because it is partial to some parts of your body. If you had dry skin, chances are that it would itch all over the body, rather than restrict itself to a couple of body parts alone. Nevertheless, it would be worthwhile to figure out if what you have is the problem of itchy skin or some sort of allergy which has affected only some part of your body. The latter is as likely to affect you as the former. What would typically happen then is that each time you perspire, the salt in your sweat would serve to irritate your skin further. There can be a couple of ways to ensure that you are not suffering from any allergenic reaction. One of the simplest ones is to go for a medical examination by a dermatologist. A skin specialist will be able to tell you if you are suffering from any allergies and will also prescribe proper treatment that you must follow.
If the problem lies in merely excessively dry skin, then you would need to make sure you keep your skin well hydrated and moist at all times. The best thing to do in this case is to have a bath with a cream based soap. This will help you tremendously. Also, make it a point to moisturize your skin appropriately after you bathe. Simply rub on a fine film of olive oil all over the itchy parts and you will be fine. If you do this while your skin is damp and warm, the result will be better. This will also help you heal, since olive oil has therapeutic properties which will work at healing your skin as well.
