An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Itch (Itching or Pruritus)
Itching can be a common problem. Itches can be localized or generalized. There are many causes of itching to include: infection (jock itch, vaginal itch), disease (hyperthyroidism, liver or kidney), reactions to drugs, and skin infestations (pubic or body lice). Treatment for itching varies depending on the cause of the itch.
First aid is a complicated subject and it is situation-specific. First aid is defined as the help and medical assistance someone a sick or injured person.

Contact dermatitis treatment may involve creams, application of cool water compresses, and applying topical steroids.
Is Poison Ivy Contagious?
Poison ivy produces urushiol, an oily chemical, that causes an itchy, painful reddish rash in people who come in contact with the plant. The rash lasts for one to three weeks. People should seek medical care for poison ivy exposure if the resulting rash covers a large portion of the body, if the rash develops on the genitalia or face, or if there is swelling around the eyes or of the throat.
