Can maple trees cause allergies. It seems when they bud, then drop the red stringy thing my allergies are at their worst. I mean even my ears get blocked and I feel as though I m under water. This when on for seven weeks. It would cause me to feel like I was in a fog and kinda affected my balance. Seen four different doctors none of which where allergist. All perscribed something different and not one of them worked. I afraid that it will happen again this spring! We ve only lived here for three years. We are surrounded by maple trees.
