My 18 year old son has has strep throat on and off 4 times in the last 3 months. Last week his throat swelled up again and became painful so he went to the doctor and he didn’t have strep but a mono spot test came back positive. He got blood work done to confirm he has mono and now he isn’t experiencing any symptoms of mono he has lots of energy his throat pain and most of the swelling went away and doesn’t have a fever, has anyone heard of anything like this?
