Did you tell the doctors that he had strep a few weeks ago?
If the strep had the phage virus then the symptoms you describe could appear after the strep infection. Be sure to tell them about the recent strep infection.
Yes, it was the same doctor, so they knew. All the tests done recently came back negative. I am thankful he seems to be fine now.
Thank you for your help. I appreciate the kindness and concern Freepers have shown.
