Allergies

Not ragweed

09/11/2009

Question:

i have allergies once a year during the end of august through the beginning of october. i don`t think it`s ragweed because i`ll have a good day when ragweed is up and a "bad" day when it is down.

Answer:

Your symptoms directly parallel the ragweed season in the eastern part of the United States. The ragweed count always lags one day behind. In addition climatic factors such rainfall and prevailing wind direction may have profound effects on day-to-day pollen counting. The height and location of the ragweed sapling locale may also account for daily differences in the count and your symptoms.
