Saturday i was putting out pines straw bales in yard & started coughing attack. it came on all of a sudden. drank water and later took alevert. it helped. today feel tired/stuffy? never had this happen before. could i have allergy now to pine straw?

It does sound like a hyperacute allergic reaction to inhaled substances. When it comes to the type of substance, it could have involved anything from mold to chemicals on the pine straw dust that might have triggered your respiratory issues. If symptoms persist would suggest seeing your local doc as a type of hypersensitivity pneumonia becomes likely.
