I took DD (7.5 months) to the doctor yesterday for a check and a vaccination. We live overseas (Eastern Europe) but private clinic, US trained doctor etc. A few days earlier I noticed a small red spot on her arm, which wasn't there before. It is like a blood blister, but tiny and not a blister - if you see what I mean. I sometimes get them myself. Anyway, the doctor seemed worried about it and had me take pictures of it and took blood tests and talked about specialists. I asked why, but she said 'lets not worry til we know something'. The thing is, I don't even know what to google - what could it be? It is just one spot, not others.
