Urticaria
Urticaria – also known as hives, weals, welts or nettle rash – is a raised, itchy rash that appears on the skin. It may appear on one part of the body or be spread across large areas.
The rash is usually very itchy and ranges in size from a few millimetres to the size of a hand.
Although the affected area may change in appearance within 24 hours, the rash usually settles within a few days.
A much rarer type of urticaria, known as urticaria vasculitis, can cause blood vessels inside the skin to become inflamed. In these cases, the weals last longer than 24 hours, are more painful, and can leave a bruise.
Treatment
The patient is advised to wash the face with soap and shampoo the hair as frequently as possible and avoid greasy cosmetics and hair oils. Along with this proper homoeopathic treatment must be taken. Acne patients need not observe any dietary precautions because sebaceous gland is a secretary gland and blood levels of the lipids or their dietary intake has no effect on the secretion of the lipids by the sebaceous glands. The patient should be informed that the tendency to develop acne is likely to continue for a few years and thus it is preferable to have a preventive treatment and continue the same till the tendency to develop acne disappears completely.
