6year old grandson who is very tall for age, complained of sore elbow on Friday he fell twice from flying fox at school and landed on same elbow. On inspection, no heat, no apparent swelling. can wiggle fingers except the two middle ones cause some discomfort, didn't want to go to cricket training that he loves so that was unusual, overnight he slept OK said there was some pain though not excruciating he keeps holding it though he has it in a sling, and I noticed a small amount of swelling in the morning yesterday, Parents are a little concerned,but distracted, however Nanny is a little more as it is his right arm? could it be a hairline fracture or something to do with his connective tissues? worried Nanny!
