I managed to take a chunk out of the back of my heal last week - ow! Lots of blood initially, and then weeping for a few days. The problem is it’s exactly where my shoe rubs so I have to wear a plaster as it’s too sore not to. This means that it’s not really able to dry and scab over. It does do this over night, but then becomes gungy again during the day. Not sure if this matters. It’s not infected but want to avoid this. Is there anything else I can do? I can’t wear sandals/flip-flops as I have problems with my arches.
