Continuous itching may cause darkening of the skin of the affected area. In this section we will discuss some of the common reasons for skin rashes and the accompanying symptoms. 
Discoid Eczema
Discoid eczema is a type of skin disease and is also known as nummular dermatitis. The symptoms of this skin disease appears as oval or round plaques and can happen at any age. Discoid eczema can happen in the dry form as well as in the wet form. Dry discoid eczema also known as asteatotic eczema. can happen due to dry skin condition and is usually non itchy. Wet discoid eczema or exudative is a more acute form of this disease and is also more resistance to treatment. It can happen due to an injury, skin burn, cut or even insect bite; it is infected by staphylococcus aureus. The first symptom of it appears as a patch on either of the legs and slowly it spreads on the entire leg and may even start appearing on arms. The severe cases of exudative may happen due to autosensitisation.
Atopic dermatitis

In older children the knee region is affected and is accompanied y severe sessions of itching and acute flare ups. One may face severe discomfort in the affected region which may cause hindrance in day to day work. 
Contact dermatitis

The symptoms may be blistering eruptions and accompanied irritation. One suffering from such symptoms may contact a dermatologist to know the reason and get the treatment to avoid further complications. A patch testing may be done to know the reason behind the rash.
Gravitational dermatitis
Also known as  venous eczema, gravitational dermatitis is caused due to a damage in the veins of the leg which may have happened due to previous venous thrombosis or deep skin infection. The symptoms of this disease may show up as a discrete patch in the leg and gradually affect the entire leg up to ankles. The affected skin may show up symptoms like red scaly skin with rough crust and cracks. High vein pressure causes the red blood cells to leak from the cracked region and due to this the surrounding skin may also be discolored. If not treated on time then it may lead to further complication like atherosclerosis deep hard tissue, ulceration and autosensitisation (general rash). These were some types of common rashes of leg along with accompanying symptoms.
