Hives itching and welts are caused by mast cell degranulation, causing the production of the protein histamine. When the mast cells of the body detect antigens (anti-body producing substance caused by a foreign substances or illness) they release a number of enzymes in response. During this process histamine is released causing the capillaries to swell and leak fluid into surrounding tissue. The ultimate result is hives itching and welts from the leaking fluid under the skin. These welts can occur anywhere on the body, taking on a different form when they appear on the face. In rare cases a person may suffer from both hives and angioedema (http://www.emedicinehealth.com/hives_and_angioedema/article_em.htm).
Hives Face Welts – Angioedema
While hives generally occur on the body, a different form of hives called angioedema mostly occurs on the face. Angioedema is a form of hives that occurs in the deeper layers of the skin tissue creating larger welts and severe swelling that may itch or also burn (http://www.mayoclinic.com/health/hives-and-angioedema/DS00313). Swelling occurs in the area around the mouth and eyes, sometimes causing them to swell shut. Other areas angioedema can occur are the throat, genitals, hands, tongue, and feet. Swelling of the throat can be life threatening and immediate medical attention should be sought. Angioedema differs from common forms of hives and the treatment necessary tends to be more intense. In most cases of severe angioedema hospitalization is required with the administration of IV fluids to increase blood pressure, and IV prescription drugs to counter severe allergic reactions and anaphylactic shock. Non-allergy related forms of angioedema are termed idiopathic and may be due to stress, thyroid problems, deficiencies in iron or vitamin B12, and dental, sinus, and gallbladder infections. Angioedema can be caused by a reaction to ACE inhibitors prescribed for high blood pressure. Different from a traditional medicinal allergy, ACE inhibitor angioedema symptoms can be delayed and only occur in 1 in 500 people.
Hives Itching and Welts Relief
To relieve the itching and burning sensation of hives itching and welts on the face it is recommended to rinse your face with cool to cold water three to four times a day and use cooling compresses with anti-inflammatory ingredients to help with swelling. Your head should be kept above your heart using extra pillows when sleeping or lying down making sure that fluids continue to drain and reducing swelling. It is important that if you experience hives on your face that you seek treatment as over the counter remedies will not adequately address the issue and breakouts will continue to occur.
