I am twenty-nine weeks pregnant and for the last week I have been experiencing a constant dull ache near my ear and hairline that sometimes tingles. i did have a period of 4 days of bad migraines following the initial ache, and once they subsided I am still experiencing this strange sensation. Sometimes pain radiates down to my jaw and to my forehead and right side of head, and feels quite warm. Any ideas? I have been to the doctor and obstetrician and they couldnt pinpoint anything other than migraines and the pregnancy making them unuual in pattern. Why is this dull ache however still present?
