After playing in the backyard , amongst many trees & other debris , my 10 year old daughter has 4 bites on her arm which initially were itchy , became inflamed , have an opening on the surface & feel numb. We have been to the doctor received antibiotics and a cream however we are now concerned about the numbing as this was not mentioned to the GP. Does she need a blood test , are there any other precautions we need to do.
