I had a brain tumor when I was ten and now thirty years later discover that somewhere along the way I caught a virus. Symptoms where so random (cold extremities, waking up in the middle of the night not being able to breathe for 30+ seconds, anxieties +depression) I thought they were after effects of chemo or radiation. Then in my thirties I stared getting bad digestive issues, saw a gastroenterologist and my primary Dr. couldn't find anything either. So I had to do the research myself and tell my dr to test my blood antibodies here at the Mayo. Now at almost 40 I have Chronic Epstein Barr.
So to answer your question yes recurrance is always possible. And do your own research people, listen to your own individual bodies. I was unfortunately a minor then so they told my parents a lot more than they did to me, but I really regret not reading up on anything when I was of age.
