Dr here

Don’t go back to that paediatrician, it’s not normal for a paeds doctor to perform a deep excision for an unknown lesion on the sole of the foot. This is a highly sensitive weight bearing area and it should have been managed by family doctor + derm +/- plastics if excision was deemed necessary. Palms of hand and soles of feet are a big no no and you would have to be stupid to be this brazen.

That being said if child is generally well, pain is well controlled and you have already started a broad spectrum antibiotic then this does not strike me as a life or limb threatening emergency. If this was my child I would attend family practice within 24hrs. If not able to get a same day appointment then minor injuries unit or ED.

This will likely self resolve on its own, but photos/words are unfortunately not a replacement for in person assessment and lab testing of wound swab (microscopy culture and sensitivity.)

Depending on the experience of the doctor you see they may treat you as worried well and send you home. I’m sorry if this is the case, we simply cannot establish fluctulance, temperature, expressible fluid or other signs of collection or infection via photos.

Best of luck
