Dermatology Lloydminster - A rash on the skin is usually defined as a change to the skin in its color, appearance or texture. A skin rash could effect the whole skin or may be localized on one specific part of the body. Rashes can often cause the skin to itch, become dry, bumpy, painful, blistered, cracked, swollen or warm. Normally, rashes could cause the skin to change color. The treatments and causes for rashes differ considerably depending on the diagnosis. The diagnosis is formed by considering various factors like the rashes' overall appearance, what the patient's job is, other symptoms, family history and what the person may have been exposed to. The diagnosis can in fact confirm any number of health issues.
The rash can help to indicate certain related symptoms and signs that are common to specific diseases. Measles for example, can give a rash which is called an erythematous, morbilliform, maculopapular rash. This usually presents itself a few days after the fever begins and classically it presents at the head and after that works its way downwards.
The most common causes of a skin rash include anxieties, food allergies, medicines, dyes and insect stings and bites. Jewelry made of nickels and zincs have been found to be allergens. Skin contact with an irritant often results in 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 ringworm, from sunburn or heat exposure, from friction due to chafing of the skin, and from skin diseases like for instance acne or eczema.
Bacterial and viral infections could lead to a rash on the skin. The chickenpox, smallpox, measles and cold sore viruses can lead to distinct and uncomfortable rashes. There are some uncommon causes of rashes including: lead poisoning, Lyme disease, pregnancy, autoimmune disorders like for instance psoriasis and of course repeated and frequent scratching on a particular spot.
There are lots of potential causes of a rash, making the evaluation more difficult. In order to acquire an accurate evaluation, a health provider may have to do a completely thorough history. For example, what is the person's job? Are they taking any kind of medication regularly? Has the person recently traveled to whichever exotic locations? Normally, a complete physical examination would help in order to determine the origin and cause of the rash.
Particular Factors to Include in the Examination Are:
When referring to the appearance of the rash, is it like for instance purpuric, which is typical for vasculitis and maningococcal disease, or is it sandpaper and fine as found with scarlet fever? Is the rash consisting of plaques with silver scales that is usually seen with psoriasis? Or does the rash consist of circular lesions with a central depression, which is normal of molluscum contagiosum or small pox?
How is the rash distributed on the body? With chickenpox, like for example, the vesicles will follow the hollows of the body. They are therefore more prominent on 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 neck, armpits and groins. These lines are called Pastia's lines. There are not many rashes that affect the soles of the feet or the palms of the hands, however this can be seen in spotted fevers or rikettsia, secondary syphilis, foot, mouth and hand disease as well as guttate psoriasis and even in kertoderma blenorrhagica. The symmetry of the rash is another feature to think about. Like for example, herpes zoster often just affects one side of the body during an outbreak and does not cross the midline.
It is normally good advice never to scratch a rash, since any scratching could cause it to spread. It can be tempting to softly rub the affected area to be able to provide temporary relief but it is better to avoid contact with the affected areas completely.
