I had a c-section and experienced severe headaches the day after my daughter was born. I have had two neurologists diagnose the headaches as low pressure headaches. I have had three blood patches. Each time the headaches improved for a couple of days and then returned. I had a cisternogram which failed to find the leak. I have awakened every morning for the past 14 weeks with a dull headache which increases in intensity as the day progresses. Some days are worse than others. On the really bad days I can't get my head off the pillow. I am concerned because they did not find the leak when I had the cisternogram.
