Gardasil and medical assistant

23 years old, Had my 1st gardisal shot almost exactly 24 hours ago! Felt kinda weird all throughout the day, but dismissed it. Around 3 am I was awakened by an extremely upset stomach and severe diarrhea. I called my doctor office and spoke to a medical assistant and she stated that none of the doctors where in the office but if I could go to an emergency room to go to the er! I assumed from her response that I shouldn't be having these symptoms, but she didn't want to say that. I used my entire hour lunch to nap and almost fell when I tried to get up. My heart feels like it is going to jump out of my chest. Cramping in my stomach and I'm extremely scared to eat anything because the smell of food makes me lightheaded and. My best friend has had the shots and she said her's went okay so I agreed to go ahead and get the shot.....worst mistake !
