For about 10 months I have had, off and on, a pressure on the left side of my head above my ear. It sometimes hurts when I touch this area. Almost 2 months ago I got a headache in the back of my head on the right side. It also comes and goes. About the same time I started having tingling spots on my face, mouth, tongue and ears. This too comes and goes. Sometimes I have dizziness. When this started I went to my family doctor who sent me to the ER. They did blood tests, EKG and scanned my head and everything was normal but it continues. What should I do?
