Hi @barbus22 and welcome to Connect. That must be exasperating and frightening being unable to find a reason for your son feeling so awful.

I wanted to share this thread on Epstein-Barr Virus as @cummings3 has a similar story to yours: https://connect.mayoclinic.org/discussion/treatment-for-chronic-epstein-barr/?utm_campaign=search&pg=1#chv4-comment-stream-header

I also wanted to introduce you to fellow Connect members @mrmie and @momnxtdr as they have experienced similar symptoms themselves or with a loved one and may be able to help you find answers or provide support.

Back to your son, when will you hear about your test results? Have you set up an appointment with an infectious disease doctor?
