As flowers blossom, so do allergies.
And now that spring has sprung, allergy season is kicking up throughout the U.S.
According to the Asthma and Allergy Foundation's Spring Allergy Capitals report, which highlights the worst cities for allergy sufferers, this year Jackson, Mississippi is taking the number one spot due to high pollen and the population’s heavy reliance on allergy medications.
The report took into account tree pollen scores, medicine utilization by patients suffering from allergies, and the city’s number of board-certified allergists per patient.
The border town of McAllen, Texas slipped this year to the number four slot. Of the top five cities on the list, only McAllen scored worse than average on all three of the factors used to determine the rankings.
Out of the top ten cities, Tennessee took three spots and was the only state with multiple cities on the list.
Continuing a trend the AAFA has seen over the years, 15 of the top 25 cities this year were in the South.
"Our spring listing usually features cities from the southeast and deep south, and the #1 spot is almost always a southern city," Mike Tringale, AAFA's vice president of external affairs, said in a statement.
Below is the list of the top 10 worst spring allergy cities for 2013:
