Dermatology Sudbury - A rash on the skin is typically defined as a change to the skin in its texture, color or appearance. A skin rash could effect the whole skin or may be localized on one specific part of the body. Rashes can usually cause the skin to itch, become bumpy, dry, painful, blistered, cracked, swollen or warm. 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 elements such as what the patient's occupation is, the rashes' overall appearance, different indications, family history and what the individual may have been exposed to. The diagnosis may in fact confirm whatever number of health problems.
Having a rash appear anywhere on the body may indicate related symptoms and signs which are common of specific diseases. For example, the rash in measles is known as an erythematous, morbilliform, maculopapular rash. This typically presents itself a few days after the fever starts and classically it presents at the head and then works its way downwards.
There are numerous common causes of rashes like for example: anxiety, food allergies, medicines, dyes and insect bites and stings. The metals zinc and metal are commonly found in jewelry and are commonly known allergens also. Skin contact with an irritant usually causes hives. These raised portions of skin can become itchy, red, inflamed, swollen and painful. Rashes could also result from a reaction to vaccination, from a fungal infection like ringworm, from friction because of chafing of the skin, from sunburn or heat exposure, and from skin diseases like acne or eczema.
A skin rash can also become present due to a bacterial or viral infection. Like for example, the viruses which lead to chickenpox, smallpox, cold sores and measles can be uncomfortable and distinct. There are several uncommon causes of rashes including: lead poisoning, Lyme disease, pregnancy, autoimmune disorders like psoriasis and of course frequent and repeated scratching on a particular part.
There are a lot of potential causes of a rash, making the evaluation harder. In order to get an accurate evaluation, a health provider may need to do a completely thorough history. Like for instance, what is the patient's job? Are they taking any kind of medication regularly? Has the individual just traveled to any exotic locations? Normally, a complete physical examination would be helpful in order to determine the origin and cause of the rash.
Specific Elements to Include in the Examination Are:
The appearance of the rash, for instance, is it sandpaper and fine as found with scarlet fever, is it purpuric, that is normal for meningococcal disease and vasculitis? Is the rash consisting of plaques with silver scales which is normally seen with psoriasis? Or does the rash consist of circular lesions with a central depression, that is typical of molluscum contagiosum or small pox?
How is the rash distributed on the body? With chickenpox, like for instance, the vesicles would follow the hollows of the body. They are thus 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 known as Pastia's lines. There are not many rashes which affect the palms of the hands or the soles of the feet, although this could be seen in spotted fevers or rikettsia, secondary syphilis, hand, foot and mouth disease as well as guttate psoriasis and likewise 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.
Normally, 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 area in order to provide temporary relief but it is better to avoid contact with the affected parts completely.
