Diagnosis | Skin rash on thigh

Diagnosis

To determine the correct diagnosis and cause of a rash on the thigh, the entire skin must be examined once. This simple examination of the skin allows possible suspected and differential diagnoses to be determined without much effort. Further diagnostic tools, such as blood tests, smears or fungal preparations continue to provide information about causes such as infections, autoimmune diseases, allergies or chronic skin diseases and help to confirm or rule out the suspected diagnosis. Sampling provides information about the cause and is particularly useful in the case of blistering autoimmune diseases such as pemphigus vulgaris or bullous pemphigoid.

Which symptoms are typical?

The accompanying symptoms of a skin rash on the thigh can be very diverse and depend on the underlying cause. Shingles, for example, manifests itself through itching, pain and a feeling of tension in the affected skin. Fungal infections, on the other hand, are mainly characterized by itching and scaling of the skin. A bacterial infection, such as phlegmon or erysipelas, is usually accompanied by general symptoms such as fever, nausea and fatigue. An unpleasant odor or the discharge of pus are also typical for abscesses or bacterial infections.

Itching with a rash on the thigh

A very common accompanying symptom of various rashes is itching. For most people affected, itching subjectively leads to the highest level of suffering.Not only does it cause painful scratching of the skin, but it also robs most of those affected of rest and sleep. Itching is a very typical symptom of parasitic diseases, such as itchy mites, bedbugs or similar.

Other infections, such as fungal infections, also cause itching. A terrible itching continues to cause allergic skin rashes. In this case the itching is not localized, but spreads much more over almost the entire body.

Contact allergies, neurodermatitis or intertrigo can also cause severe itching. Often itching cannot be treated causally, but symptomatically. So-called antihistamines, such as Fenistil, are mainly used to treat itching.

As a local measure, menthol or capsaicin ointments can be applied to the affected areas. However, these are only suitable if the skin changes are limited to the thigh. Such ointments are not suitable for application to large areas of skin.
