Dermatology Leamington - A skin rash is defined as a change of the skin that affects its texture, color or appearance. Rashes can be localized in one part of the body or they could affect the entire skin. Usually, rashes could cause the skin to itch, become dry, bumpy, painful, blistered, cracked, warm or swollen. Often, rashes can cause the skin to change color. The causes and treatments for rashes differ considerably depending on the diagnosis. The diagnosis is formed by taking into account various factors like for example what the person's occupation is, the rashes' overall appearance, different indications, family history and what the patient may have been exposed to. The diagnosis could in fact confirm whatever number of health problems.
Having a rash appear anywhere on the body could indicate related symptoms and signs which are common of particular diseases. Like for example, the rash in measles is referred to as an erythematous, morbilliform, maculopapular rash. This typically presents itself a couple of days after the fever starts and classically it presents at the head and after that works its way downwards.
There are numerous common causes of rashes including: anxiety, food allergies, medicines, dyes and insect stings and bites. The metals nickel and zinc are usually found in jewelry and are normally known allergens too. Skin contact with an irritant usually causes hives. These raised portions of skin could become itchy, red, inflamed, swollen and painful. Rashes could even result from a reaction to vaccination, from a fungal infection like for example ringworm, from friction because of chafing of the skin, from sunburn or heat exposure, and from skin diseases like for example eczema or acne.
A skin rash could also become present due to a viral or bacterial infection. For example, the viruses that lead to smallpox, chickenpox, measles and cold sores could be distinct and uncomfortable. There are various uncommon causes of rashes including: pregnancy, lead poisoning, Lyme disease, autoimmune disorders like for instance psoriasis and of course repeated and frequent scratching on a specific spot.
There are lots of probable causes of a rash, making the evaluation harder. To be able to obtain an accurate evaluation, a health provider may have to do a completely thorough history. Like for instance, what is the patient's job? Are they taking any type of medication regularly? Has the person recently traveled to whatever exotic locations? Often, a complete physical examination would help to determine the cause and origin of the rash.
Particular Elements to Include in the Examination Are:
When referring to the appearance of the rash, is it for instance purpuric, that is usual for meningococcal disease and vasculitis, or is it sandpaper and fine as found with scarlet fever? Does the rash consist of circular lesions with a central depression, which is normal of small pox and molluscum contagiosum? Or is the rash consisting of plaques with silver scales that is normally seen with psoriasis?
What is the distribution of the rash? Like for example with chicken pox, the vesicles often follow the hollows of the body; therefore, they are most prominent along the depression of the spine on the back as well as in the hollows of both shoulder blades. The rash presented with scarlet fever becomes confluent and forms bright red lines in the skin creases of the groins, neck and armpits. These lines are known as Pastia's lines. There are not many rashes that affect the palms of the hands or the soles of the feet, although this can be seen in rikettsia or spotted fever, secondary syphilis, mouth, hand and foot disease as well as guttate psoriasis and likewise in kertoderma blenorrhagica. The symmetry of the rash is one more feature to think about. For example, herpes zoster normally only affects one side of the body throughout an outbreak and does not cross the midline.
Usually, it is good advice not to scratch the rash. This is due to the scratching causing a spread of the rash. It can be tempting to gently rub the affected part to be able to provide temporary relief but it is better to avoid contact with the affected areas completely.
