I wonder if you and your wife caught whatever you son had. What you have described as the symptoms is here in my area as well. Your wife is right...this isn't something to play with and I'm glad you saw the doctor today. Rest and plenty of fluids helps.
I hope that you and your family will be feeling better very soon.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
