What to do if your hands and feet itch due to allergies

I believe that there are always one or two friends around us who are allergic. Either they are allergic to protein and they will stay away from any food related to protein, or they are allergic to seafood and will never eat seafood in their life. In addition to these, you will also hear them say that once they come into contact with allergens, various reactions will occur in their bodies, such as rashes on the limbs, general weakness, etc. What should I do if my hands and feet itch after an allergy?

This kind of skin itching is mostly caused by allergies. It is recommended to actively take oral drugs such as Cyproheptadine, Bitrex, Vitamin C, Fangfeng Tongsheng Pills, etc., and the condition will improve.

Pruritus is a symptom of skin disease characterized by only skin itching without primary skin lesions. According to the scope and location of skin itching, it is generally divided into two categories: systemic and localized.

Causes

1. Generalized pruritus is often a concomitant or initial symptom of many systemic diseases, such as uremia, biliary cirrhosis, hyperthyroidism or hypothyroidism, diabetes, malignant tumors and neuropsychiatric pruritus. The external causes of systemic pruritus are related to environmental factors (including humidity, season, biological or chemical stimulation in the working environment), topical medications, the use of highly alkaline soaps, and the decreased secretion function of the patient's sebaceous glands and sweat glands leading to dry skin.

2. The causes of localized pruritus are sometimes the same as those of systemic pruritus, such as diabetes. Anal pruritus is often related to pinworm disease, hemorrhoids, anal fistula, etc. Vulvar pruritus is often related to leucorrhea, trichomoniasis, vaginal fungal disease, gonorrhea and cervical cancer. Scrotal pruritus is often associated with local high skin temperature, sweating, friction, and fungal infection. The occurrence of itching is mainly caused by the release of chemical mediators such as histamine, substance P, kinins and proteases.

Finding the cause of the disease and avoiding the inducing factors are the key to prevention and treatment. Avoid using scratching, rubbing, and hot water to relieve itching. Live a regular life, wear loose clothes, and don't bathe too often. Avoid drinking alcohol, strong tea, and spicy foods such as chili, pepper, and mustard. Patients who are mentally stressed and emotionally disturbed should pay attention to rest and appropriately change their unhealthy living environment.
