The chemicals also cause...

Are any tests needed?
Usually no tests are needed. The rash is very typical and is easily recognised as hives by doctors. In a few cases it is clear what caused the rash from the events leading up to it, for example if recently stung by a nettle or starting new medication.
A symptom diary
A symptom diary may be helpful in working out if there is a specific cause. A diary might also show if the rash relates to stress, exercise or sunlight. It may help rule out certain causes.
Skin-prick allergy tests
In some cases, if it appears to be related to an allergy, tests such as skin-prick allergy testsmay be helpful. Tiny quantities of substances which might cause an allergy are placed on the skin in a special order. If the skin reacts, there may be an allergy to that substance.
Often no treatment is necessary, as the rash commonly goes within 24-48 hours. A cool bath or shower may ease the itch. Calamine lotion or menthol 1% in aqueous cream can help with itching, although if it is left on for too long the itch may come back. These can be bought without a prescription. Once it is clear what causes the hives, it may be pos...

The cause of the rash is not known in more than half of cases and it is commonly a one-off event. However, hives may be more serious in t...
Inducible urticaria most commonly occurs in healthy young adults. As a rule, hives triggered by physical stimuli tend to improve and become less troublesome with time (often going, or being much less troublesome, after 2-5 years). Acute hives usually last less than six weeks. Most cases last 24-48 hours and in some cases the rash only lasts a few h...

Apr 5, 2024 · A stinging nettle rash is a painful, red rash that appears after you come into contact with the stinging nettle plant, which is found throughout the U.S. The acid in the tiny hairs covering the leaves and stem of the plant causes the rash.
Urticaria (also known as hives, weals, or nettle rash) is a superficial swelling of the skin (epidermis and mucous membranes) that results in a red (initially with a pale centre), raised, and intensely itchy rash.
The name urticaria is derived from the common European stinging nettle 'Urtica dioica'. A weal (or wheal ) is a superficial skin-coloured or pale skin swelling, usually surrounded by erythema (redness) that lasts anything from a few minutes to 24 hours.
