Introduction
White small round spots appearing on the feet, accompanied by pain and itching, may be caused by various factors including drug allergies, warts, blisters, etc. Certain medications might trigger allergic skin reactions, leading to the appearance of white spots on the feet; the exact cause should be analyzed according to specific circumstances. Additionally, it could also be due to athlete's foot (tinea pedis). It is recommended to seek medical attention promptly for diagnosis and treatment by a qualified physician.
Generally, the appearance of small white spots on the feet accompanied by pain and itching may be caused by various factors, including drug allergies, warts, blisters, and others. Specific analysis should be based on individual circumstances. Details are as follows:
1. Drug Allergy
Certain medications may trigger allergic skin reactions, leading to small white spots on the feet, along with symptoms such as itching and pain. Under a doctor's guidance, the medication can be discontinued or switched to an alternative.
2. Blisters
Blisters may develop on the feet after prolonged wearing of tight shoes or physical activity. These blisters might contain clear or whitish fluid. Maintaining good foot hygiene—such as washing feet regularly, changing socks frequently, and wearing breathable footwear—can help prevent them. With medical advice, topical treatments like bifonazole cream or mupirocin ointment may be used. If necessary, oral antifungal medications such as terbinafine tablets or itraconazole tablets may be prescribed.
3. Warts
Small white round spots on the feet could also result from a viral wart infection. Warts typically appear as small skin elevations or granular lesions. They can be removed under professional medical care using treatments such as laser therapy or cryotherapy (freezing).
In addition, these symptoms might also be due to athlete’s foot (tinea pedis). It is recommended to seek timely medical attention for accurate diagnosis and appropriate treatment by a qualified healthcare provider.
