Erythema is a skin inflammation on the fatty layer of the skin. On spreading of the legs, they give the skin a red appearance along with pain and tender lumps. The lumps could vary in size from one to five centimeters. They usually affect the front part of the legs. Erythema is a self-limited skin condition and even if no treatment is taken, it can clear off by itself within a period of 3 to 6 weeks. After healing, it may leave behind a bruised appearance over the area where the fatty layers had been destroyed. This, however, fades with time.
Dermatitis is a skin inflammation characterized by red, dry and itchy skin. If the condition gets severe, it could also lead to painful cracks, crusty scales, and fluid filled blisters. There are many types of dermatitis and the diagnosis is done based on the category of dermatitis affecting the skin. The symptoms, as well as the treatment of these different types of dermatitis, are fairly similar.
Cold sores are also known as fever blisters. Some people frequently get cold sores while others may not get them throughout their lifetime. When they do come out, they feel very itchy and painful. Cold sores are, however, a treatable condition.
Folliculitis is a condition in which the hair follicles get inflamed. This could develop in any part of the body that has hair, but is most common in the beard area, arms, buttocks, backs, and legs.
Boils are infections occurring in the hair follicle or the oil glands. When the pores get clogged, the dirt and oil trapped inside become the breeding ground for bacteria. First, the skin turns red after which a tender lump develops in the area. After about a week, the infected area forms a bigger lump and starts accumulating pus inside it. Boils usually occur in areas such as buttocks, armpits, face, neck, shoulders and sometimes eyelids. The ones occurring in the eyelid are called sty or stye. If the boils occur in a cluster, the condition is known as a carbuncle.
