question: As of a few months ago my daughter has been complaining of a tight feeling in her chest ... it would come and go. We did take her to get a chest x-ray and nothing was found. The doctor thought it might be a small allergic type reaction to her eating too much tomato based foods (i.e. spaghetti sauce etc..). I recently came across an article about the dangerous side effects of Gardasil (papillomavirus vaccine) and tightness in chest is a rare symptom that was listed. I am greatly concerned now that it could be what is happening. Her first shot was given on 5/5/2010 and the second shot on 9/14/2011. Should I be concerned at this point 3yrs later? Is it related?
