For the longest time I've had little round 1/16th inch itchy sores on my feet that just appeared there and I notice it's spreading up my legs where my socks are normally touching my skin, now that I think about it. Any idea what possible causes of this are? They don't seem to be healing, but that may be because I haven't payed much attention to it.
Welcome to the MedHelp forum!
Diabetes, psoriasis, hypothyroidism, contact dermatitis, atopic dermatitis and malnutrition should be ruled out first. Itchy feet with tiny white blisters could be eczema, fungal infection, dermatitis, contact allergy with allergens like soap, chemicals etc. If you itch between toes too, there are chances that it is scabies, fungal infection and sweat dermatitis. See if your feet come in contact with particular grass, shrubs, chemical etc. It can also be an infection under the skin or cellulitis. Do discuss this with a skin specialist as confirmed diagnosis is not possible on net. Take care!
