Hi, I've Had A High Temperature For Almost 2 Months

Hi, i've had a high temperature for almost 2 months now with feelings of nausea, fatigue and illness. I visited my local doctor and he told me it was probably a virus and that i simply had to wait it out. I continued to experience these symptoms over the next month and a half, then late last week i also began to experience pressure in my head and a stiff neck. This pressure eased after 2 days but i was left with a sickly feeling in my head, bad concentration and light-headedness. This illness is really taking its toll on me both physically and mentally. My doctor is sending me in for a blood test on monday. A 2nd opinion on my symptoms would be much appreciated.
