Hi! I have had a headache everyday for the last 2 weeks. I have a history of sinus headaches and migraines, but have never had a headache last this long without being able to eventually get lasting relief. The first week I tried Exedrin and Sudafed, which usually relieves most of my headaches, but the pain kept returning. I read that taking Exedrin over a period of longer than 2 or 3 days could cause rebound headaches, so I stopped taking it, but was so uncomfortable that I tried taking Midrin, which my doctor had given me some time ago. Unfortunately, it didn t relieve the pain either. Since then, I ve gone back to the Exedrin, but have tried to only take it when I ve absolutely had to. I ve been trying to figure out what is going on, and one different beverage I ve been drinking lately is LeCroix carbonated water. Could that possibly contribute to my headaches? Do you have any ideas of what could be causing them or what I might try to relieve them? Thank you! Lisa Butterworth
