Hoping someone can suggest the best way to help DD with her foot. She was bodyboarding in the sea about 3 weeks ago in Cornwall, and suddenly hurt her foot - thought at first she had hit it on a rock or something. I suggested she get out and let me look at it, but after a minute or two she said it had stopped hurting and wanted to stay in. Later she said it was sore again when walking on it, so I took a look but there wasn't much to see - a slight whitish line maybe, I thought perhaps she had cut it on a sharp shell or something, but there wasn't any blood and later she felt fine again.
However since then, it has mostly been fine (she's been doing sports and so on), but once in a while it suddenly starts hurting her again and she finds walking on it painful. I've looked at it again but there's very little to see - no puffiness or signs of infection, but what looked like maybe a couple of tiny punctures and possibly something inside (but just tiny dark dots if anything, so it's hard to be sure). So I'm now wondering whether she might have something like teeny bits of spines or something in there?
I'm not sure what to do though as there's so little to see, nothing to get hold of etc. so I doubt taking her to the doctor would help and don't want to waste their time, especially as most of the time it doesn't even hurt. But I wondered whether there's anything we can do to try and get anything that might be in there out, especially as it's still bothering her occasionally nearly 3 weeks later. Would soaking it/hot water help for example, or is there anything we could put on it? Thank you!
