<s>[INST] Hello, i have reoccurring small dots like the end of a biro on my right foot only. They come ovr a week or 10 days, become itchy and when itched fill with fluid like a blister. i have them aroung the heel and down the right side of the foot and between my big toe. after they have been itched and ooze they scab over and them the skin is normal a few days after. they reappear every few months [/INST] Thanks for your query at HCM!It seems you have some sought of fungal infection (dermatophytic). I suggest you get your fasting and random sugar get tested. You must collect the fluid by pucturing of blister and send for tests like gram staining, microscopy for fungal elements, culture- aerobic/anaerobic bacterial and fungal tests. Follow up with investgations for proper treatment. In meanwhile after sampling you can apply some triple action cream.Take care! </s>
