Approximately 20 percent of the U.S. population gets hives, also called urticaria, at least one time in their life. Hives are red, swollen welts and can appear anywhere on your body. They are sometimes itchy. Hives can last anywhere from a few minutes to several weeks, however, each individual welt should disappear within 24 hours.
Causes of Hives
Usually, hives are caused by an allergic reaction to either a drug or certain foods. If you have other allergies, you are more likely to get hives. For some, the cause of the hives is obvious. An allergic reaction to certain foods, such as peanuts or shellfish, may cause hives within minutes or hours of eating the food.

Allergies to pollen, animals, latex or other substances
Infections and illnesses, such as thyroid disease or hormonal problems
Sun exposure or exposure to heat or cold

This very common generator of cervical, thorocic and lumbar pain connects one boney segment to the other, helping to form the entire spinal chain or column like a big long Slinky. These joints are extremely important for supporting motion such as twisting, bending and turning. Without these facet joints, the spine would feel like one big broomstick. Because the spine is constantly in motion, the joints are always being stressed and can become worn out, swollen and painful.
Arthritis in the facet joints is technically called Facet Arthropathy . You'll find that term on radiologists' reports examining the spine by X-Ray, MR, or CT imaging. Facet arthropathy can be seen in those who do not have any pain and in those as young as their 20s. In reality, these jo...
