I was mowing lawn for the last time this yr and there are a lot of leaves in the yard. I began mowing and about 2sailed in I began weasing and coughing bad I stopped coughed Caught my breath and began mowing again same thing happened. I litterally ran through the last part and came inside jus hacking and coughing until I changed clothes and washed my face then the cough subsided. Am I allergic to trees or grass I ve mower lawn during the summer and had no problems.
