Usually, rashes may cause the skin to itch, become bumpy, dry, blistered, cracked, painful, warm or swollen. usually, rashes could 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 a variety of factors like the rashes' overall appearance, what the person's occupation is, family history, what the person may have been exposed to and different symptoms. The diagnosis may in fact confirm whatever number of health issues.
The rash may help to indicate some connected symptoms and signs which are common to specific diseases. Measles for example, could give a rash that is referred to as an erythematous, morbilliform, maculopapular rash. This typically presents itself a couple of days after the fever begins and classically it presents at the head and after that works its way downwards.
There are many common causes of rashes like for instance: anxiety, food allergies, medicines, dyes and insect bites and stings. The metals zinc and metal are usually found in jewelry and are commonly known allergens too. Skin contact with an irritant usually causes hives. These raised portions of skin could become red, inflamed, itchy, swollen and painful. Rashes may even result from a reaction to vaccination, from a fungal infection like ringworm, from friction due to chafing of the skin, from sunburn or heat exposure, and from skin diseases like for instance eczema or acne.

There are many possible causes of a rash, making the evaluation more difficult. To be able to get an accurate evaluation, a health provider may have to do a completely thorough history. Like for instance, what is the individual's job? Are they taking any kind of medication regularly? Has the patient recently traveled to whatever exotic locations? Usually, a complete physical examination will help to be able to determine the origin and cause of the rash.
Certain Factors to Include in the Examination Are:
The appearance of the rash, like for instance, is it sandpaper and fine as found with scarlet fever, is it purpuric, that is typical for vasculitis and meningococcal disease? Is the rash consisting of plaques with silver scales that is normally seen with psoriasis? Or does the rash consist of circular lesions with a central depression, which is typical of molluscum contagiosum or small pox?
What is the distribution of the rash? Like for example with chicken pox, the vesicles usually 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 groins, neck and armpits. 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 rikettsia or spotted fever, secondary syphilis, hand, foot and mouth 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 through 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 could be tempting to softly rub the affected part so as to provide temporary relief but it is better to avoid contact with the affected parts completely.
