Irritation or Allergic Reactions

Many of us have felt the itch that accompanies wearing a wool sweater or coat. Likewise, many people with itch are suffering from a reaction to chemicals in laundry detergents or fabric softeners, soaps, cosmetics or perfumes that are irritating the skin. Food allergies and drug reactions are also commonly associated with itch, and an unexplained itching after trying a new food may be an indication of an allergic reaction.

What Can I Do?

If you suspect that you’re having a topical reaction to a cosmetic, laundry detergent or other chemical, wash the affected area with a mild soap and gently pat dry. If you suspect that you are having a reaction to food or drug, contact your medical health provider. If your itching is accompanied by more serious symptoms, such as shortness of breath, seek medical help immediately.

Stress

One of the most common causes of itching is psychological - due to stress, anxiety or other emotional problems. Stress can be both the cause of itch, and it can aggravate itch from other sources.

What Can I Do?

To attack the cause of a stress-related itch, try stress-busting exercise routines or yoga, or find outlets for that stress. If the stress level is severe, consider making an appointment with a professional, who can help with coping mechanisms.

Skin Infections Or Infestations

Skin infections and infestations, which can be caused by a number of sources and occur in many areas of the body, are often the root of itch. Genital itching, which may be accompanied by a burning sensation or pain, in both men and women can occur as a result of genital infections or sexually transmitted diseases (STDs). Women may suffer from yeast infections, which cause vaginal itching, and fungal infections in the groin (tinea cruris), commonly called jock itch, can also be a source of itch. Skin infestations, through head lice and pubic lice, are also responsible for itching. Scabies is a highly contagious skin condition caused by an infestation of the itch mite Sarcoptes scabiei that is known to cause an intense itch that is particularly severe at night.

It's only natural to want to scratch those itches. If they aren't short lived, a trip to the doctor may be warranted.
