I have chronic migraine/fibromyalgia. Sleep study ordered, AHI is 26.1.One sleep specialist this is sleep apnea and I need CPAP, other says its fine?

Go to primary doc. the specifics about the sleep study are important. abnormal sleep patterns must be correctly interpreted, as the treatment is usually long term. migraine prevention is not complicated ie beta blockers, midrin, fibromyaogia is treatable , and sleep should be fixed first.
