I very often get headaches, but usually in the cooler months. I think most are migraines, but some may be sinus headaches, too.
I think there was another recent post about
headaches--maybe last week or so*? The ideas there may be helpful. Feel better soon. I know what it's like to have ongoing headaches and it doesn't make life easy!
Edited to add: *See Klambert1's post on migraines ("Migraines anyone?") on July 14th. I know you didn't say they were specifically migraines, but the tips there may be of help--I hope so!
