hi mono can last from 1 week to 4 weeks and a lot longer i don't think you was really clear of it properly and this is why you still have it. but it is a bit of a bugger to get rid of and can keep repeating sometimes even years later so do watch out in future. but please get your self well. good luck
could i have mononucleosis again after being better for just two weeks? . i got mononucleosis nearly four weeks ago took about two weeks off school and have been back for two weeks. now i am beginning to feel symptoms like i did at the beginning last time headache tired and runny nose i thought his might just be a cold but now my throat is starting to hurt. i don't have a fever but i didn't have much of one last time is it possible it has come back so quickly?
