Dermatology Peterborough - A rash on the skin is normally defined as a change to the skin in its appearance, texture or color. A skin rash could effect the whole skin or could be localized on one particular part of the body. Rashes could often cause the skin to itch, become dry, bumpy, painful, blistered, cracked, warm or swollen. usually, rashes may cause the skin to change color. The treatments and causes for rashes vary considerably depending on the diagnosis. The diagnosis is formed by considering different elements such as the rashes' overall appearance, what the patient's job is, family history, what the individual may have been exposed to and different signs. The diagnosis can in fact confirm any number of health issues.
Having a rash appear anywhere on the body can indicate connected symptoms and signs which are common of specific diseases. Like for instance, the rash in measles is called 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 afterward works its way downwards.
There are numerous common causes of rashes such as: anxiety, food allergies, medicines, dyes and insect stings and bites. The metals nickel and zinc are often found in jewelry and are normally known allergens as well. Skin contact with an irritant often leads to hives. These raised portions of skin can become itchy, red, inflamed, swollen and painful. Rashes could even result from a reaction to vaccination, from a fungal infection like ringworm, from friction due to chafing of the skin, from heat exposure or sunburn, and from skin diseases like eczema or acne.
Viral and bacterial infections could result in a rash on the skin. The chickenpox, smallpox, measles and cold sore viruses can cause uncomfortable and distinct rashes. There are several uncommon causes of rashes like: pregnancy, lead poisoning, Lyme disease, autoimmune disorders like for example psoriasis and of course repeated and frequent scratching on a particular part.
As there are so many potential causes of a rash, the evaluation can be somewhat difficult. A health provider may need to do a completely thorough history to be able to acquire an accurate evaluation. Like for instance, what is the patient's job? Are they taking any kind of medication on a regular basis? Has the person recently traveled to any exotic locations? Normally, a complete physical examination will be useful 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, that is typical for meningococcal disease and vasculitis, or is it fine and sandpaper as found with scarlet fever? Is the rash consisting of plaques with silver scales that is often seen with psoriasis? Or does the rash consist of circular lesions with a central depression, that is normal of molluscum contagiosum or small pox?
What is the distribution of the rash? For example with chicken pox, the vesicles normally follow the hollows of the body; thus, they are most prominent in the hollows of both shoulder blades as well as along the depression of the spine on the back. 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 referred to as Pastia's lines. There are not many rashes that affect the palms of the hands or the soles of the feet, although this could be seen in spotted fevers or rikettsia, secondary syphilis, mouth, hand and foot disease as well as guttate psoriasis and also in kertoderma blenorrhagica. The symmetry of the rash is one more feature to consider. Like for instance, herpes zoster normally just affects one side of the body through an outbreak and does not cross the midline.
It is generally good advice never to scratch a rash, since whichever scratching can cause it to spread. It can be tempting to softly rub the affected area so as to provide temporary relief but it is better to avoid contact with the affected parts completely.
