What Causes Pressure In Head And Tingling Sensation In Spine?

I have fibromyalgia & take meds for this as well as chronic anxiety and depression. In 2007, I became ill with what the dr thought was strep, & was laid up for a month. During this time, I experienced strange symptoms, one of which was the sensation of an electrical wave or current going up & down my spine. Since then, I feel as if there is a heavy cap over the top half of my head, making it difficult to even raise my eyebrows (know this sounds silly!), and often have headaches / pulses of pain there. Have had everything from my sinuses to my ears checked, but nothing. One dr. thought I should be treated for a fungal infection... Any help you can give me would be great! Cindy
