(Undated) -- Spring is here, and so are seasonal allergies. Millions of Americans suffer from allergies, but according to the Asthma and Allergy Foundation of America, not all cities are created equal. An annual ranking names Louisville, Kentucky as the worst city for spring allergies, followed by Memphis, Baton Rouge, and Oklahoma City. The ranking is based on pollen levels, use of allergy medications and how many allergy specialists there are in the area.
