Hi, I have asthma and use an albuterol inhaler. I just started taking probiotic fiber about two weeks ago because I often have digestive trouble. For about a week, I have feeling tightness my chest and today, for the first time, I see a slight swelling in my neck. I m not having difficulty breathing, but I can tell there is something wrong. Can I be having an allergic reaction to the probiotic? If so, what should I do besides stop taking the probiotic and trying to get in to see my doctor? Thanks, Kay
