Tamara Lillet, M.A., offers an intriuging look at this subject. I'm wondering about the possibility that some FM patients might experience both allergic & non-allergic rhinitis. I definitely have allergies & have been under treatment for them for decades. Several of my allergists over the years have told me I also have weather related symptoms. Might it be that we can have both & that is a complicating treatment factor? Has anyone else encountered this?
