A long-distance runner was left with enormous pus-filled orange blisters on her legs after suffering from devastating sunburn during a 110km jog.
Mum-of-two Julie Nisbet, 34, was running from coast to coast along Hadrian's Wall between Carlisle and Newcastle for an ultra-run called "The Wall".
But after completing the 21-hour mega-marathon on Saturday last week, Nisbet noticed small sacks of pus bubbling up across her red-raw calves, according to the Daily Mail.
After "screeching in pain" and covering the blisters in bandages, she went to hospital - but the "gruesome" blobs only grew larger.
