A few months ago I had fever, bad pressure headaches. Since then I have had recurring headaches, facial pressure and aching behind my right eye as well as clicking sound in my head/neck joint area. I eventually went to doctor when symptoms did not go away. Was given a weeks antibiotic for possible sinus infection and had blood test. Antibiotics had little effect but doctor said I had had glandular fever. But my current symptoms seem much more like sinusitis or something else yet doctor told me to go away for 6 weeks to see if it goes away. Doctor did not believe that symptoms might have a separate cause. My question is what do you think is the likely cause of my symptoms. I don't want to suffer for another 6 weeks before going back to the doc.
