A rash with temperature becomes a frequent harbinger of various serious ailments. Moreover, it can manifest itself both on the body of a child, and of a teenager, an adult.
The rash, which often accompanies itching, can affect not only the skin, but also the mucous membranes. Not for nothing that reddening with suspicious bubbles can be found even in the throat, and not only on the stomach. By itself, a rash rarely acts as an independent disease, which usually involves the course of the disease without fever. In most cases, it suggests the beginning of the development of the disease of infectious or non-infectious origin.
When is rash most often accompanied by fever?
Each external manifestation of this symptom has its own distinctive features, which allows to determine the true pathology, which is the root of the disease.
For primary classification, the principle of localization is used, which means a detailed study of lesions on the face, legs, back. It is usually easier to diagnose diseases where the mentioned symptoms occur, if you understand whether the rash has affected only one part of the body, or is spread all over the skin.
The next point of the state with increasing temperature is the division of the proposed diseases into two broad categories: infectious, non-infectious.
The first group includes the majority of childhood infections, among which are chickenpox, rubella, some other pathologies, which are easier to get over in childhood than being an adult.
This also includes meningitis, herpes, which is characterized by a small rash, accompanied by transparent blisters. First, the affected area around the mouth or genitals mercilessly itches, and then the bubbles burst, which leads to the coating of the dermis little attractive crusts.
Among other infectious representatives of the deviations, which is characterized by a high temperature in addition to red, pinkish skin, have shingles type zoster. Syphilis, typhoid, and infectious mononucleosis also fell here.
According to a similar scheme, when a rash appeared, there is a development of a number of typical non-infectious abnormalities such as systemic lupus erythematosus, psoriasis, neurodermatitis, seborrheic dermatitis, folliculitis. Slightly less often in medical practice are scleroderma, pityriasis versicolor, Gilbert's disease.
But the skin tumors of a malignant, benign nature of oncological nature are generally considered separately, depending on the severity of the lesion. Localization of them together with rashes of various types has no significant limitations, which means the possibility of tumor nucleation on:
Regardless of whether the deterioration of well-being is accompanied by some other symptoms, such as complaints that the affected area hurts, it is not necessary to do without consulting a dermatologist or therapist.
If we consider the most common abnormalities with two typical signs, to which a headache is occasionally added, then the unspoken leader is called an allergic reaction. She can make herself felt both by the baby on her neck and by the elderly person in the groin.
The primary source of the disease becomes an allergen. They can become anything from household dust, pollen during flowering, food. But in the latter case, you need to learn to distinguish between allergies and classic food poisoning, which also includes diarrhea, vomiting, to which dehydration of the body is then added.
Template allergies include:
- low-grade fever.
To get rid of the root of the problem, you first have to make an appointment with the doctor. He will conduct an initial examination to rule out some other serious diseases with similar symptoms. Only after that the patient with skin disorders will be sent to undergo a laboratory study. If the victim only had a slight allergy, which began to go off on day 3 after the allergen was removed, the treatment will be carried out according to the standard scheme.
But when the reasons have not been fully studied, it is necessary to pass the so-called allergic tests. Their result will allow to reveal the primary source of why the victim is regularly tortured with a cold, swelling, rash, and even occasionally nausea.
At the physiological level, the pathogenesis is explained by the production of a biologically active substance, which is called histamine. When the mechanism of its production fails, the body begins to signal skin abnormalities, which are often accompanied by temperature changes. And along with the fact that a person literally “burns,” they are found in a state where the victims are diagnosed with lower temperature readings.
Prescribe a course of treatment with the involvement of detoxification measures, as well as antihistamines can only an experienced doctor. He will determine that the virus settled on the feet or elsewhere. When trying to self-medicate many people are interested in the fact whether there can be one that treats the patient one thing, but in fact he has a completely different disease.
This is often found in clinical practice, because not everyone can conduct a qualified examination, recognizing enlarged lymph nodes, other special markers. It is all the more difficult to consider any deviations in the mouth when the rash is localized in the sky. But often sore throat, snot say not at all about skin lesions, but about the fact that the person was knocked down by a common sore throat.
Children's diseases with fever and rashes
Considering all types of ailments, including two presented signs, physicians separately distinguish the three most common childhood diseases. This is about:
- chicken pox.
Sometimes more scarlet fever is added to it.
In case of all illnesses from the list it is impossible to wait for the time when the irritating symptoms would have subsided by itself.
In order for measles to pass, it will take a lot of effort, because on the background of skin problems in humans, the temperature also rises to 40 degrees.
Typical features of measles are phasing, because the spread of the rash always follows a typical pattern:
- omission below;
- coverage of the lower limbs on or about the third day.
Besides the fact that the patient is worried about spotty skin, already on the second day he faces pathognomonic grayish spots in the mouth. The spots on the mucous layer of the cheeks have a red rim. But they disappear as quickly as they appear.
Rubella, which usually affects children of kindergarten age, with high-quality treatment is not dangerous. A great threat is noted only for women carrying a fetus, as in some cases, gynecologists even insist on the need for an artificial abortion.
First, a punctate rash appears on the face, and then rapidly spreads further onto the hands, thighs, covering even the calf. But if you compare the severity of brightness with measles, rubella is more pale. If you do not look closely, you can never notice any significant changes in appearance.
The main markers of pathology is considered to be lymph nodes, which are inflamed. They are localized:
- behind the ear, in the posterior cervical region;
- in the occipital zone.
Even a non-professional at palpation will note that the nodules are struck by swelling.
The final childhood disease is called chickenpox, which is awakened by the herpes virus. From this conclusion, it becomes clear why blisters with smallpox are so similar to those that pursue patients during the acute stage of herpes simplex disease settling near the lips.
The skin elements in a similar situation are located throughout the body, and while on the head they are just beginning to “tie”, somewhere on the forearm, the life cycle of the rash comes to an end. Each new portion is accompanied by the fact that the temperature indicators are again creeping up.
Separately is infectious mononucleosis, which has all the same two signs. But the difficulty here is added by the fact that the clinical picture is often blurred. The only stable beacon is an increase in lymph nodes in the back of the neck.
To prevent the deterioration of health, when roseola turn into life-threatening and health elements, it will be necessary to pass a blood test. With the help of such laboratory testing it will be possible to determine the specific stage of the disease.
How to eliminate symptoms in children and adults?
For most of the most common diseases, doctors have not yet developed a specific treatment, using only the generally accepted rules aimed at facilitating well-being. This means that with the same chickenpox, you will have to be treated and wait until the spots disappear themselves.
To prevent secondary rash, doctors advise using antiseptic spectrum techniques. It is enough just to make sure that the victim does not have an allergy to the components of the pharmaceutical composition, otherwise an atypical prickly heat will be added to everything else.
To maintain health at a sufficient level, sometimes immunomodulators, vitamins, minerals, antiviral drugs are added to the course of treatment, and the daily diet is revised in the direction of its enrichment. But antibiotics because of the stomach are not allowed to use by everyone, and only if absolutely necessary, according to current indications.
In this case, it is much more difficult for adults, for whom the majority of childhood diseases, is much more difficult, because they have low resistance. Patients older than fifteen years are often additionally weakened by muscle weakness, diarrhea, and photophobia.
Those adults who are undergoing a course of chemotherapy, are taking corticosteroids, or have a weak immune system, spoiled by another type of load, are at risk of those who are more susceptible to illnesses with a rash, fever.
In any case, when detecting the mentioned symptoms, it is required to consult a doctor immediately. It can be difficult for average people to detect a rash with rubella and secondary manifestations of syphilis, which can serve as a foundation for a fatal mistake if you want to engage in self-medication. To prevent this, you will need the advice of a dermatologist.
