Keep in mind that i am a 19 year old university student, usually fairly healthy until last year.
I was recurrently sick with bouts of symptoms last year (may, june, august, september), which my doctor presumed to be glandular fever. He took repeated blood tests and my full bloods and LFT's were all normal. Later in the year (in september) the symptoms recurred and were more severe than every other time. I couldn't access my usual gp as he himself was sick and off work at the time. So instead i visited the local ED.
After various tests they concluded i had abnormal liver function and pneumonia. The dr there told me that i was an alcoholic with a high chance of hepatitis and needed to have a back up blood test to rule hepatitis out. She also prescribed me Diazepam for the 'expected' alcohol withdrawals.
My follow up bloods (and ultrasound) ruled out hepatitis or any other liver problems.
Since this time (Sept 2006) i have experienced severe fatigue/exhaustion both physical and mental (effecting my concentration, memory and attention span), insomnia, waking up feeling like i need more sleep after 10 hours of sleep, shortness of breath and lethargy on exertion. Muscle fatigue and muscle weakness, joint and muscle pains and recurrent viral infections (i would get a cold that lasts 4 or 5 weeks). I cannot remember a time i have not had a sore throat, swollen glands, a cough or a runny nose. I have also been far more moody and emotional than usual which i think is due to the frustration of being sick day in day out.
In march i went back to my doctor as the exhaustion was really affecting my study and physical ability to attend classes at uni. He finally decided to do all sorts of bloods including Epstein-Barr Serology (which he hadn't done before) and everything came back normal apart from the EBV. Therefore my 'symptoms' definately was glandular fever.
Since then, until now i have still been experiencing the same symptoms, but now i am getting frequent headaches (i think are migraines) that i never had before. The symptoms of which include pain which gets worse with time, usually on one side focussed around the back and side of my eye, extremely painful as i can barely move, sensitivity to any sound and bright lights. With the photosensitivity lasting a few days afterwards. Some days i wake with these headaches and go to bed with it, waking up the next morning still having it. Pain killers (paracetamol and/or ibuprofen) just reduce the pain slightly for a short time period. The other day the headache pain was so intense it hurt worse if i moved any of my facial muscles.
I guess what i am wondering is where do they draw the line between post viral fatigue and chronic fatigue syndrome? This has been going on for 9 months and i don't really feel as though it is improving.
