What should I do if my foot develops blisters and swelling during lactation?

Blisters and swelling on the feet during lactation may be caused by localized skin infections, such as athlete's foot caused by fungal infection. Fungal infections tend to occur in humid and hot environments and are often accompanied by itching and peeling. They could also be blisters caused by excessive local friction, followed by an inflammatory response. Another possibility is contact dermatitis, triggered by allergens such as shoe or sock materials.

As medication should be used cautiously during lactation to avoid affecting the baby through breast milk, if the blisters are due to friction, the affected area can be disinfected with iodophor locally to prevent rupture of the blister, allowing it to be absorbed naturally. If a fungal infection is suspected, topical antifungal creams, such as clotrimazole cream, may be used, but should be applied after breastfeeding, with close observation of the baby for any discomfort. If it is contact dermatitis, avoid contact with suspected allergens and apply cold compresses appropriately to relieve swelling.

If symptoms persist or worsen, such as fever, increased pain, or spreading redness and swelling, medical attention should be sought promptly.
