What could cause blisters at my palms and feet? (photo)Skin, Hair & Nails
I have had an outbreak of blisters at my palms and feet for 4 weeks. What are possible causes, and how can it be treated? Thank you.
Thank you for the close-up photos, they are very informative. From these photos, there are a few conditions that come to mind, but it will be ideal for you to be assessed by a dermatologist as certain tests need to be done to ascertain the cause.
1. Dyshidrotic eczema: This is a type of eczema that usually affects hands and feet. It can be very itchy and lead to tiny blisters forming on the palms and soles. If the small blister breaks, there can be clear or yellowish fluid that flows out. You may have a history of eczema affecting other areas of your body. This can be treated with topical steroid creams, moisturisers and anti-itch medicines.
2. Bullous tinea (fungal infection with blistering): Fungal infections of the hands and feet can lead to blister formation, and this is more common on the soles. One will be prone to fungal infections if the area is moist for prolonged periods of time (eg sweaty feet), background of diabetes and frequent wetwork without proper hand hygiene. The circular pattern of peeling skin and rash on the sole does suggest a fungal infection. A simple skin scrape test will reveal fungus and can be treated with appropriate topical or oral anti-fungal medications.
3. Scabies infection: If there are also small red spots in between the webspaces of the fingers and toes, scabies infection is another possibility. This condition is extremely itchy and there may be a history of close contact with someone infected with scabies. Anti-scabies medicines are needed.
I hope the above information helps. Do consult a dermatologist for a proper assessment.
Take care and happy new year!
