My daughter , who is 5, went to the dr today because of a soar throat and fever. They did a strep test which came back Negative but the dr said that those tests are sometimes not 100% accurate but based on what she saw it seemed to be strep so she gave her an antibiotic. Yesterday, before her appointment, she was complaining that the bottom left side of the back of her head was hurting and it felt like a bruise. When we were at the dr today I mentioned it and she said she probably just ment her throat. My daughter is very smart and when she pointed it out it was clearly the back of her head. We came home and again, started complaining about the "bruise". I cannot see any redness or bruising so I'm a little concerned. Any thoughts?
