I am new to this forum. My 6 yr old son was playing the back-yard and came back complaining about a bug that bit him. I looked and there was a small circular bug-bite behind his neck in his upper back. There was also a little blood there. I checked him again today and it has become a bulls-eye rash as there is swelling around the bite. My son is otherwise not displaying any symptoms - the 'bug' bit him yesterday at around 4pm. But today is Memorial day and the after-hour doctor's office said that I should bring him in tomorrow as there is no urgency at this point. Unfortunately, I could see no tick or bug around him or in his clothes that I could keep with me for testing.
I am looking for some advise - is this time sensitve and should I take my son to the hospital immediately or should I wait till tomorrow? Thanks,
