I Have Left Sided Facial Pain. It Has Been A

I have left sided facial pain. It has been a problem for a week or more. If I lie on left side, very painful and face swells markedly. Resolved quickly if I revert to right side. Feels like fluid behind eardrums, every time I hiccup or burp.
Yes I am a migraine sufferer but this is not anything like my usual migraine or its syndrome. I often get syndrome without the pain.
Feeling of need to blow nose without producing any mucus.
