I have had endo for 8 years, but was diagnosed 8 months ago during a laparoscopy. I have noticed in the last few years that my allergies have gotten worse and I attributed it to moving to the opposite side of my state (a lot of ragweed and pollen). But I have moved back to my stomping grounds and have been here for 6 months and my allergies have continued to get worse. I have to take sudefed or benedryl daily to deal with the constant sinus headaches and nausea from post nasal drip. I have undergone allergy tests before and they have come back negative. I was wondering if anyone else has dealt with Endo and Allergies and how they combat it.
