I have had a headache for over 2 weeks now and it is getting worse and worse. It is accompanied by dizziness, nausea and a sense of "spinning" when I lay down or turn my head. For the last year I have had these blackouts and now I am starting to realize I have substantial memory loss during times when I didnt think I had a blackout. IE cannot find my car, losing things in the house, forgetting movies and shows I just watched, the day of the week, etc. Also, for the last week I have had numbness and tingling in my left arm. (I am left handed, if that matters) I saw my DR and he prescribed tension headache medicine, muscle relaxors and something for the nausea. Its not working. He also ordered a CAT scan and a neurology apt. When I called to schedule, they told me it was 6 weeks for an apt. I feel like my symptoms cannot wait that long. What do I ask my doctor? He seems concerned but doesnt seem to know much. Any suggestions will help, thank you.
