"There was no pain at the injection site.  Both my boyfriend and I received the shot and had close to the same experience, except I have been having extreme vomiting, after 2 weeks of getting the shot.  We both experienced a severe headache starting within 30 minutes of receiving the shot that lasted about a day and a half, followed by severe diarrhea that is still going on, three weeks from the time of injection with nausea.  He is having lots of muscle aches still, while I&#039;m having severe pain up one of my legs near the hip.  Neither of us had problems or sickness before the shot that would indicate it was something other than the shot."
