Hi Pranab, Thanks for the query. I completely understand your concern and I hope I am able to help you for the same. Looks like your husdand has developed cellulitis over the feet. We can try conservative treatment first but if the condition continues to worsen , then you might need to consult a physician. Avoid touching it too much. Avoid using any kind of cold dreams or hair oils..as it might increase the lesion You can start using any topical antibiotic/antiseptic cream(like mupirocin cream) over the lesion for 2-3 days Take some pain killers along for relieving the associated pain and discomfort keep foot end elevated esp at night in order to prevent any swelling Oral antibiotics are required if the cellulitis increases, which a dermatologist / physician can examine and suggest Take care Wishing your husband speedy recovery Dr Geetika Paul
