My husband has seasonal allergies and after mowing the grass yesterday he was sneezing and having sinus issues. Today he woke up fine and went to the gym. Before the gym he ate his usual meals and took a prpre - workout. After the gmy he had a bad headache and blurred vision. He laid down and then threw up. After throwing up and said he feels better and the vision is fine. Now he has cold chills. He works out 5 to 6 days a week so exercise and hydration are normal. Any suggestions? Bethany
