Is itchy calves in summer caused by moisture?

There are many reasons for itchy calves in summer. From the perspective of traditional Chinese medicine, it may be due to heavy moisture. From the perspective of Western medicine, it is a symptom of skin allergy and itching. The most common causes are allergic dermatitis and eczema. It should be checked and treated promptly. To find the triggering factors, stay away from allergens in daily life. In daily life, we should emphasize rationality.

1. General treatment 1. Find the cause and provide appropriate treatment. 2. Avoid various external stimuli, pay attention to skin hygiene, combine work and rest, strive to live a regular life, and limit smoking, alcohol, strong tea, coffee, spicy and other irritating foods.

II. Systemic treatment 1. Oral or injection of antihistamines, 5-hydroxytryptamine antagonists and sedatives. Such as chlorpheniramine (chlorpheniramine), diphenhydramine, cyproheptadine, cetirizine, astemizole, terfenadine, loratadine, cimetidine (cimetidine), ranitidine, *** (diazepam), etc. These drugs can be selected according to the condition. H2 receptor antagonists alone have a certain effect on the pruritus caused by Hodgkin's disease and polycythemia. 2. For those with severe itching, 10% calcium gluconate can be injected intravenously or 0.25% procaine hydrochloride and vitamin C 1.0-2.0g can be added to 500ml of normal saline or compound sodium chloride solution and dripped intravenously. Naloxone can be used for patients with intractable pruritus, but it is potentially addictive. 3. For menopausal or senile pruritus, male patients can choose to use 50 mg of testosterone propionate intramuscular injection 2 to 3 times a week, or 25-50 mg of nandrolone phenylpropionate tablets intramuscular injection 2 to 3 times a week; female patients can take 1 mg of diethylstilbestrol orally once a day. 4. For those with dry skin, vitamin A 50,000 U/d can be taken orally or injected. 5. For itching caused by cholestatic diseases or uremia, cholestyramine (cholestyramine) can be used, 5 to 8 g per day. 6. Rifampicin can be used for itching caused by primary biliary cirrhosis, but it is toxic to the liver, so further observation is needed to determine its safety. 7. For itching with obvious mental factors, tricyclic antidepressants such as doxepin can be used.

3. Local treatment 1. For those with mild secondary damage, 1% calamine carbonate lotion, antipruritic lotion, various steroid emulsions (such as 0.025% fluocinolone emulsion, 0.25% fludrocortisone emulsion, 5% benzocaine emulsion or lotion, 1%-3% borneol emulsion, 5%-10% black pomegranate oil emulsion or ointment, etc.) can be used externally. 2.
