Oh my goodness, that IS a nasty looking bite
. I swell up and get a huge red ring around mosquito
and spider bites, but it's never this large.
I would also suggest running her to the doc's, or maybe call them first and talk to a nurse, just to be on the safe side.
Also, regarding the hematuria, my 9 yo DD has had both gross and microscopic hematuria (she's had micro as long as I can remember). She's had a CT scan and they found 2 renal cysts.
