In the past couple months I have experienced 4 excruciating headaches up the back of my head a few hours after nodding off. The only relief I get is by standing or sitting in an upright position. I am going through perimenopause (irregularity. hot flashes, night sweats) don't know if any correlation. Have had headaches through out my life but nothing as scary or as painful as these.
Thank you for any information you can give,
Kim
