Introduction
Red rashes on the top of the foot may be caused by mosquito bites, contact dermatitis, eczema, or other reasons, and treatment should be based on the specific cause. Mosquitoes usually pierce the skin with their mouthparts, triggering an allergic reaction that results in red rashes and itching. Under a doctor's guidance, topical application of erythromycin ointment or oral administration of levocetirizine hydrochloride capsules may be used for treatment.
Rashes on the top of the foot may be caused by mosquito bites, contact dermatitis, eczema, or other reasons, and treatment should be based on the specific cause. Details are as follows:
1. Mosquito bites
Mosquitoes usually pierce the skin with their mouthparts, causing an allergic skin reaction that results in red rashes and itching. Under a doctor's guidance, topical application of erythromycin ointment or oral administration of levocetirizine hydrochloride capsules may be used for treatment.
2. Contact dermatitis
This may occur due to switching to new shoes or socks, causing the skin to react allergically to certain components in them, resulting in red patches. Under a doctor's guidance, treatment may include topical application of compound acetic acid dexamethasone cream or oral intake of methylprednisolone tablets.
3. Eczema
This is an inflammatory condition affecting the epidermis and upper dermis, caused by various internal and external factors. In the acute phase, skin lesions are primarily characterized by papules and tend to ooze. Under a doctor’s guidance, topical medications such as desonide cream or tacrolimus ointment can be applied for treatment.
In addition to the above causes, rashes may also result from allergic purpura, pressure purpura, or athlete's foot. It is important to wear loose, comfortable footwear and avoid prolonged walking.
