Nerve Problem?

Here are my symptoms:

Pain in middle of back
Pain in ribs - mostly left but sometimes right side
Pain in joints - knees, hips, ankles
Sciatica
Lately I've been getting itching in my knees, elbows, ankles, and shoulders. Also, my back were the pain is and my head. If I brush my hair or put it up in a pony tail or just pull on it lightly, my head will start to itch like crazy.

There's no rash with the itching, just sometimes look red in the joints.

Does this sound like some kind of nerve problem?

I've had xrays on my back and ribs and am waiting on the results. I just wonder if maybe there are some pinched nerves that are causing the pain and itching? It feels like I've been rolling around in fiberglass or I have thousands of fleas biting me. Like a prickly feeling all over my body.


Now I'm getting tingling all over my body and last night it felt like I couldn't get a good breath, like I was being sufficated. Today I have a headache and my head feels like it's too heavy for my body. My BP was 114/57 this morning.
