Help with diagnosis

I'm wondering if anyone can help with a diagnosis as my symptoms have my doctor stumped. I'm also not sure if I'm in the right forum.

Three months ago I started getting sharp shooting pains in my neck followed by swollen glands, earache and fatigue.
Three weeks ago I had sharps pains in the back of my knees and they became very sore. Since then my arms have become heavy and aching with tingling in my fingers and my neck has been stiff with excruciating dull and pin-like head pains that cover the whole of my head. I also have fleeting sharp pains in various places around my body but these come and go.

I've had blood tests which came back fairly normal apart from slight anaemia. My doctor has no idea who to refer me to. Can anyone advise?

Appreciate your help
