Something is terribly wrong with me, anyone have any ideas ?

It started almost 3 weeks ago. I was getting sharp shooting pains in my hands fingers, arms- prodominantly in the left side. It has worsened and I get stabbing pains all over my body now. Feels like a needle moving through my veins and/or bone.

I've also experienced acute pain in the Jaw , the lower jaw and below the ears. Two types of sensations; sharp shooting pains and a feeling like you tried to stop a sneeze and it forced pressure in a cavity in your face.

The last two days I've been really weak and sore, and periodic cold flushes running through my entire body, And that terrible feeling like my blood is running cold. I was also shivering the other night and was hugging the heater until my legs were burnt. My Veins seems more visible than usual, they look very dark blue and I see traces of veins where usually I wouldn't.

I had blood tests a few days ago, but still no results. Feels like my body is shutting down from some kind of infection. Anyone know what is happening to me ?
