Are there suddenly red spots on your hands?

The human skin is very sensitive, especially for people with sensitive skin. If you don't pay attention, dermatitis will take advantage of the opportunity. For example, if our hands suddenly become red, we don't have to worry too much. It is likely caused by dermatitis. You can use calamine to clean it first. If the symptoms are relieved, just eat a light diet. If the symptoms cannot be relieved, it is best to see a doctor in time.

Dermatitis seriously troubles the patient's life. How long will it take for allergic dermatitis to heal? Many people suffer from allergic dermatitis, but because they do not go to regular hospitals for treatment, the disease recurs repeatedly and cannot be cured. This is because patients have not found a scientific treatment method and need to pay attention to daily care.

The causes of allergic dermatitis can be divided into two categories: primary irritation: mainly caused by strong acids, strong alkalis, lice and certain highly irritating or highly concentrated chemicals. This type of disease has no individual selectivity and no incubation period. It can immediately cause acute skin inflammation in anyone who comes into contact with it.

Allergic dermatitis does not occur immediately after the first contact, but often takes a latent period of 4-20 days (7-8 days on average) for the body to become sensitized. If the body is exposed to the substance again, dermatitis may occur in about 12 hours (usually no more than 72 hours). This type of allergic reaction is the most common type of contact dermatitis.

The speed of recovery of allergic dermatitis depends on the severity of the patient's condition. Allergic dermatitis generally has an acute onset, with clearly defined erythema, papules, and papulovesicles occurring at the contact site. In severe cases, blisters or bullae may occur at the red and swollen site, and erosions may occur after the blisters rupture. The location and extent of dermatitis are consistent with the contact object. Itching and burning sensations are common and are very distressing to the patient. Patients are advised to go to a regular dermatology hospital for examination and treatment in time.

If the patient receives timely treatment and stays away from the cause of the disease, he or she can recover quickly, but the disease may relapse if the triggering factors are encountered again. What you should pay attention to is to avoid re-irritating the local area, avoid scratching the local area with your hands as much as possible, do not use hot water or soapy water to clean the local area, and do not apply highly irritating drugs locally. Pay special attention to not applying hormone drugs locally casually. These are common factors that can easily worsen the disease or reoccur. Try to understand the basic rules of the occurrence and development of dermatitis as much as possible, cooperate with the doctor's treatment, and build confidence in curing the disease.
