I took my 16 month old to the park yesterday and since then, she's had a large, bright red, hard bump on her left arm. Yesterday, it was very small but today it is huge. It looks very red, swollen, and has gotten a lot bigger than it was yesterday. Yesterday, it was the size of a pea, today, the size of a quarter.
I don't know what she was bitten by.
It also has a huge, yellow centre.
What could have bitten her to cause such a reaction and how can I treat it? Is it something we'd need to see the doctor about?
