These are batches of raised, white or red itchy welts of numerous sizes that appear and disappear. While in most cases, these go away within a few weeks or even less, for some individuals they are a long-term problem. The cause for chronic hives is usually not identified but treatment can help with symptoms. An outbreak that looks quite alarming, first thing in the morning can be completely by afternoon only to be back in full vigour later in the day.
What causes chronic hives?
These are an inflammation of the skin that is triggered when certain cells release histamine and other chemicals into one's blood stream, causing small blood vessels to bleed. However, the exact cause for chronic hives is not fully understood, hence triggers can be difficult to pinpoint. Chronic hives are also thought to be caused by an autoimmune disorder that may be linked to another health problem such as Lupus or Thyroid disease. Heath, pressure, cold or any other environmental stimuli may worsen chronic hives.
The symptoms associated with chronic hives include:
• Last for six weeks or more.
• Small round wheals, rings or large patches that may change shape.
• Occur in batches and appear on the face or the extremities.
• Individual hives can last from 30 minutes to 36 hours.
• Majority of the people who have chronic hives also have Angioedema; the signs of this include swelling of the skin around the lips, eyes, hands, feet, genitals and inside the throat.
• Angioedema may itch less, but cause severe pain or burning sensation.
Seek medical assistance if you have the following:
• Severe hives
• Feel lightheaded and difficulty breathing
• Feel you're throat is swelling
• Hives that do not respond to treatment or continue to appear for more than a few days
