Your question is extremely vague - you have not provided any description of what you are suffering from at all. Skin irritation can be a long list of things; the symptoms can vary greatly, and so can the causes. And as with any health problem, treating skin irritation effectively depends upon correctly identifying the cause of the problem. Since you have not mentioned your symptoms at all, it is impossible to diagnose your problem or suggest any specific treatment. You should visit your doctor for a proper physical examination of your symptoms. Your doctor will then be able to prescribe appropriate treatment and other measures for your condition. At the most, we can point you to a few possibilities, and give a few general guidelines to handling skin irritation.
Since you don't know what is causing the irritation, the best treatment for now would probably be a cold compress. Wash the affected area gently with plain water (avoid using soap, in case it causes further irritation), dry it with a soft cotton cloth, and then apply the compress. The best cold compress for skin irritation would be to simply dip a soft absorbent cloth in cold water, squeeze out the excess water, and then place the cloth on the affected area for a couple of minutes. Repeat this at least thrice, and repeat the whole procedure three or four times a day.
In many cases, skin irritation is simply a mild and temporary reaction to some substance or material that your skin has come in contact with. This may be certain cosmetics, jewelry, and materials in your clothing and your environment. You should of course consider the location of the irritation, and then try to think about what objects or substances have come into contact with that skin. Pay close attention to such details, so that the next time the irritation occurs, you may be able to pinpoint the cause. Skin inflammation could also be caused by an allergic reaction, which is different from simple irritation. This could be caused not just by skin contact, but also by consuming substances that you are allergic to. Detecting allergies on one's own is usually quite difficult, and it would be better to visit an allergy specialist for this.
Finally, you may have a bacterial or fungal infection that is causing the inflammation or whatever other symptoms you are suffering from. This may be a mild infection that will disappear if you keep your skin clean and dry, but such infections sometimes require medical treatment.
