There are two common types of onychomycosis: 1) fungal onychomycosis (superficial onychomycosis), which is limited to a piece of the nail surface or its tip; ② Subungual mycosis can be divided into distal lateral type, proximal subungual type and superficial white type. This type of disease starts from both sides or distal part of the nail, and then underdeck infection occurs. What symptom is onychomycosis? Let's talk about it

What symptom is onychomycosis?

Usually from both sides of the deck or the end of the start, most of the first mild paronychia, and then gradually become chronic or gradually subside. Paronychia can cause pits or furrows on the nail surface, which remain unchanged or gradually involve the nail root. Once the deck is infected, it can be cracked, brittle or thickened, brown or black. This type is common. Because of the deposition of subungual keratin and debris, the nail became loose and turbid.

It is one or more small turbid areas on the deck surface with irregular shape, which can gradually spread to the whole deck and cause the deck to become soft and sink. No symptoms, no paronychia, often in the nail bed fold skin see desquamation.

It is more common in housewives, cooks and people who are often in contact with water. Most of them are combined with paronychia, which starts from bilateral nail folds, and may have skin redness, empyema and tenderness. The nearby armour turns dark, rises high, and separates from the armour bed under it, then the whole deck is affected.

matters needing attention

High temperature and high humidity are important conditions for tinea. Therefore, tinea in summer and rainy season is more and more serious than that in winter and dry season. Some tinea germs, which are resistant to drought and cold, are still pathogenic in cold and dry seasons, which is common in northern China. The working and living environment of patients can not be ignored. The incidence rate is lower in well ventilated areas than in closed and stuffy places. The incidence is high in crowded places. Thus, occupation, work and other kinds of ringworm disease incidence rate has a great impact. In high temperature and high humidity workshop, especially in heavy clothing, the environment with poor ventilation and poor condition will be easily contracted. If there is no bathing equipment or timely bathing, the incidence rate of ringworm disease will be significantly improved.
