Hives are welts (raised, itchy, red areas) that present on the skin. They begin as a reaction to certain medications, foods, and/or bug bites/stings. Seek immediate help and call 911 if the hives begin to spread to large areas or they begin to alter your breathing.
While they can be dangerous, hives usually go away on their own in a few hours. They may persist for times lasting from months to years. To prevent hives, the best method is prevention. Keep an eye out for possible triggers. Make it a point to avoid them. Sometimes it is not possible to avoid your triggers. Then use over the counter antihistamines like Claritin or Allegra to help control the itching.
If antihistamines are ineffective, a drug approved to treat chronic urticaria in 2014 may help. It is called omalizumab, and may be able to help treat instances of allergic asthma.

Can hives urticaria be a sign of an underlying medical condition?
Yes, hives urticaria can be a sign of an underlying medical condition. While hives are often caused by an allergic reaction to certain foods, medications, or environmental factors, they can also be a symptom of an underlying health issue.
One possible underlying condition is autoimmune urticaria, which occurs when the immune system mistakenly attacks healthy cells in the body, leading to the development of hives. This condition is often chronic and can cause recurrent episodes of hives that last for several weeks or months.
Another potential underlying cause is physical urticaria, which is triggered by physical stimuli such as pressure, heat, cold, or exercise. In these cases, hives may appear in response to these specific triggers.
In some instances, hives can be a symptom of an underlying infection, such as a viral or bacterial infection. These infections can activate the immune system and cause hives to develop as a result.
Additionally, certain systemic diseases, such as lupus, thyroid disorders, and certain types of cancer, have been associated with the development of hives. These conditions can cause chronic inflammation and immune system dysregulation, leading to the appearance of hives.
