It is very common to feel some stinging or pain when applying povidone-iodine (Betadine) to a wound, as it can be harsh on healing tissues. To help your wound heal smoothly, I recommend gently cleaning it with mild soap and water or sterile saline instead. Keeping the wound moist with a thin layer of plain petroleum jelly and covering it with a clean bandage will promote faster healing and reduce discomfort. If you notice increasing redness, warmth, swelling, or pus, please have a healthcare professional look at it.
