Suggest Treatment For Headache And Fibromyalgia

Hi I am a 61 yo. female who fell while skiing and hit my head but had a helmet on. Also I fell down the steps right onto my coccyx bone just as we were leaving. I have a constant headache for two weeks but it is usually most severe in the morning when I wake up. Skiing slightly activated my fibromyalgia. I keep thinking my headache will go away but it just keeps hanging on. I am very active with yoga and dance and am 6 months out from having been treated with rituxin and fleudera for CLL. Where do you recommend I start in a workup or should I just ride it out.
