Towards the end of March, I was diagnosed with Mono and went through all the common symptoms for a total of about 4 weeks, except I really didn't experience any fatigue other than maybe 2 days. After this I was completely fine until 6 weeks later when my posterior cervical lymph nodes, tonsils and nodes closer to my clavicle swelled up again. Currently they are still swollen on and off, and I have been experiencing some fatigue and malaise as well as neck and shoulder pain on one side. I have been having a hard time finding information on mono flare ups, but I was wondering if they were really common after the initial symptoms wore off.

Also, previous to getting full blown mono, did anyone experience symptoms during the incubation period? Previous to becoming sick but after when I'm assuming I was exposed, my tonsils would swell up every other week and I'd become extremely fatigued.

Any insight would be wonderful, thanks!
