Urticaria,
or 'nettle rash', is often associated with allergy since it looks
like a reaction to stinging nettles. It forms acutely itchy swollen
patches on the skin, which usually subside quickly although occasionally
it becomes chronic. It can be caused by reaction to penicillin, certain
foods, sunlight or even stress; it is sometimes caused by pressure
from a tight garment, which is why it is often falsely attributed
to washing powder residues in clothing.
It can be treated by anti-histamine tablets
or, if very severe, by steroids prescribed by a doctor. |

 Psoriasis:
a common skin condition which is due to over-production of cells in
the epidermis with incomplete desquamation: this is what causes the
heaped-up skin areas and scaly patches. It is essential to get a doctor's
advice. |

The cause of the greasy scales and crusts of seborrhoeic
dermatitis is unknown, but it is known to be a form of chronic
eczema and psoriasis. It commonly occurs in the hair line, and
affects beards and eyebrows too. It may lead to infections:
medical advice is necessary. |
