otitis externa

I have been treated for an ear infection for going on to 4 weeks now. In total I have been given 4 lots of antibiotics including ear drops. My Doctor has told me I definately have otitis externa however, she sent me to M clinic to have microsuction. As my ear was to swollen I was given two dressings before I actually had microsuction then 1 weeks worth of antibiotic drops. On return to the clinic I was told I have a cloudy eardrum and that I would need to be referred on to a specialist. My symptoms started with a constant clear fluid dripping from my left ear a large swollen gland behind the ear. For over a week now I have had a constant frontal headache and stiff neck radiating to my shoulders. I have asked my Doctor what a cloudy eardrum is and she has told me that there are varied reasons and the specialist will probably want a CT scan to see what is actually there. I would just like to know if anyone has an idea as to what it may be from my symptoms, I'm really fed up and feel tired all of the time so much so that I feel as if I need to sleep when I'm at work and even after all the treatment I still have fluid in my ear I would be grateful for any suggestions.
