Rain and blisters

It's raining. Low clouds are swirling through the village. We're sitting waiting for it to stop and for the pharmacy to open. My compañero's feet are badly blistered on the heel so we need urgent medical attention if we're going to get to the next village of Chelva. Not so far (16 km) but down and up a depth through a gorge. We need to be in tip top condition.
