9. Knoxville, Tennessee
Knoxville enjoyed being far from the top 10 of the worst cities for spring allergies, but it all changed a few years ago when this city suddenly jumped up to the top 5.
This year, however, citizens of Knoxville are a little better off since the situation has improved a bit since the last year. Total score for this city is 81.32 which is overall above average when it comes to the factors measured but the biggest contributor to this score is the amount of allergy meds used by the people. Pollen count is somewhere around the average and there are enough physicians to help alleviate the situation.
