Please help Me - Severe Earache and Sharp Pain.......

I have had a sharp pain on the left side of my cranium for a couple of weeks now - it started out slowly and worked it's way up to a knife like pain, like a knife jabbing my head on the left side.

Also, my neck, just under my left ear was killing me - very swollen with a lot of pain and seems to be connected to the sharp head pain on the left, as if it were one connection.

And, the rining in my ears PLUS, get this, ....... the constant "swooshing" sound in my ears - the sound you get when you go swimming and there is water in your ears and you hear this "woosh" "woosh" sound.

What is this everyone - what can I do to heal this - it is scaring me because the left side is connected to issues of the heart. I put some tea tree oil on the whole area on the left side of my neck, under the ear and up the side. Wow, that really hurts.

Any ideas?
