Thank you for responding @mrmie I am 24 and I have not had an actual diagnosis of mono but I have always suffered from terrible sore throat and acute tonsillitis growing up. Prior to the onset of my current symptoms I was working part time as a waitress (I too have had to take leave) whilst completing my masters degree in law - so perhaps stress may play a part. Although I have not yet been tested for EBV, after researching recently I intend to ask my doctor to do so as many of the symptoms seem to fit my situation to a tee. I can recollect always suffering from fatigue with little ‘get up and go’ in me and finding myself needing a good 8 hours sleep at least! I have taken the liberty of supplementing myself with both vitamin C and B complex to aid my immune function alongside my vitamin D. My sister has confirmed EBV by an endocrinologist I don’t know if genetics can play part in susceptibility to the virus? But it’s certianly something I am looking into in order to get to the root of my health issues. Prior to this onset of illness I was physically healthy, apart from chronic migraines which I believe are hormone related due to my PCOS. Whatever this is it’s definitey viral but I have yet to put my finger on the cause! I’m hoping EBV is the cause just to have some peace of mind and move forward with aiding my recovery! Sorry for the long winded posts but I’ve found this forum extremely reassuring and somewhat comforting to hear people with similar experiences which confirms I am not going mad!
