Urticaria or hives can occur almost anywhere on the body. Hives on buttocks can therefore be treated as a normal case of body hives. Most cases initiate on a single part of the body such as the trunk, chest, arms, legs, and can seem to spread over several hours as old hive welts fade and new ones develop. Hives welts can be distinguished from other rashes by the raised circular forms they take. Welts can be small or grow in size to join with other welts creating large patches of raised skin. Their color can be whitish or red with a red inflamed area surrounding the welt. It is common for a case of hives to last several hours and sometimes several days. In the more extreme cases of acute urticaria, hive welts can last up to several weeks. Anything exceeding six weeks is considered chronic hives. In incidences of long-term acute urticaria, the cause can usually be isolated to an allergy with repetitive exposure, a changed mental state such as stress, illness, or immune disorder rather than cold, heat, exercise, or sun exposure.
Welts on Buttocks
In addition to acute hives caused by histamine reaction, there are several forms of hives with different triggers. Pressure urticaria is caused by the blood flow to a certain part of the body and the application of pressure. Sitting for too long in a single posture can cause hive welts on the buttocks and similarly those who wear tight pants or belts may experience pressure urticaria around the waist. Welts on the buttocks can also develop as a reaction to the detergent you use to launder your underpants or the chemicals used to clean toilet seats. If you have a case of contact dermatitis you might change your detergent to an allergy-free formula to prevent further irritation. Keep in mind that welts on buttocks differ from other rashes that may occur on the buttocks.
Hives on Buttocks – Could It Be Something Else?
In order to properly address your skin rash it is best to confirm that what you have is indeed hives. In addition to the raised welts characteristic of hives, urticaria tends to appear over the entire surface of the skin rather than in specific areas such as skin folds and joints. When examining your rash take note of the type of outbreak – welts, bumps, pustules, lesions, etc. If the condition persists you should visit your doctor as a bacterial, fungal, or viral infection may be to blame. Common examples of rashes on the buttocks are diaper rash caused by prolonged exposure of feces and urine on the skin, yeast infection, and cellulitis.
