Hi, I've been experiencing a cold for the past 3 days, the think that abnormal is I've been having a racing heart. The racing heart happened before a took my cold medicine so i know it wasn't the medicine that caused it. I'm also just all around sore. Yesterday night i was out in the cold, yelling at the football game. I'm sure that this didn't help my current situation but, I'm hoping it's not laryngitis. Thanks for your time.
