Initially, it appeared as a small red patch with a few clustered red bumps. It wasn’t swollen, but slightly itchy and mildly tender. I’ve been cleaning the area with Dettol, applying Betadine antiseptic, and doing occasional icing. Over the past 48 hours, the redness has become more localized, and now there’s a central lesion with a whitish-greyish crusty center, and a few smaller satellite bumps nearby. The central one is a bit raised, but there’s no pus, no discharge, no heat, and no significant swelling. It is not painful, but lightly itchy when touched. No fever or systemic symptoms. I’m attaching a recent picture as well. Does this look like it could be a healing insect bite, localized folliculitis, or possibly early tinea? Should I continue with Betadine or switch to something else.
